Detail:
  Pointless jumping over the generated code or inserting conditional
    instructions which will never be executed.

Detail:
  The 26-bit and 32-bit capable macros have been added.
  Header files choose which set of macros to use based on <Machine>.
  If you want the new macros, include "Hdr:APCS.<APCS>" in addition
    to the usual inclusions at the top of assembler files.
  Choices are based on the settings of macros No32bitCode and
    No26bitCode.  By default, all existing machines define these
    as {TRUE} and {FALSE} respectively.  This yields the same macros
    as before (tested in Customer F 5 build) and should yield code which
    functions on RISC OS 3.1.  Any other combination of settings is
    untested at this time.
  New assembler code should use the macros FunctionEntry, Return et al
    to ensure that they build correctly.
  New assembler code should be written to not require flag preservation
    across internal function calls and to not assume it on external
    function calls where it is possible to do so.  DO NOT simply replace
    "MOVS pc, lr" with "MOV pc, lr" as this doesn't work properly.
    Replace "MOVS pc, lr" with "Return ,LinkNotStacked"
  Do not write code which simply masks out &FC000003 from pc or some kind
    or pc originated value (eg. on r14 to attempt to remove the PSR flags
    from it.  Use the RemovePSRFromReg macro instead.
Admin:
  Tested with Customer F 5 build.
  Requires FPEmulator 4.11
  Requires Portable 0.65 (or Portable75 0.04)
  Required by any new or modified assembler code in future, pretty much.
    Such components may not necessarily specify a dependency on this
    or any other later version of HdrSrc.

Version 0.63. Tagged as 'HdrSrc-0_63'

Detail:
  New external declarations: error base, service call.
  New country declarations.
Admin:
  E-mail received 18 Nov 1999

Version 0.62. Tagged as 'HdrSrc-0_62'

  Added Window module service calls.
Detail:
  The Window module was using service calls &82880-4 (matching its SWI
    chunk).  This is now registered in the Services file.
  SWI chunk name corrections:
    Toolkit -> Toolbox
    Windows -> Window
    Menus -> Menu
    IconBar -> Iconbar
  The SWI chunk name changes affect the symbols generated in Hdr:SWIs, and
    by the newly exported header files in RiscOS/Sources/Toolbox/Common
    which use the symbols defined in ISV-SWIs as the SWI symbol prefix.
Admin:
  Pineapple have OK'ed these changes.
  New files e-mailed to Pineapple as current masters.

Version 0.61. Tagged as 'HdrSrc-0_61'

Detail:
  Start off a new range for encoding alphabets that'll only appear in fonts,
  never as territory information
Admin:
  E-mail received 13 Nov 1999.

Version 0.60. Tagged as 'HdrSrc-0_60'

Detail:
  MediaNet and RTSP SWI chunks no longer contain underscores.
  Fixed a missing allocation.
Admin:
  E-mail received on 9 Nov 1999.

Version 0.59. Tagged as 'HdrSrc-0_59'

Detail:
  All mkdir commands are preceded by do to ensure system variables
    are expanded before mkdir sees them.
  Relies on the header directory variables instead of <Build$Dir>
    since the export directories may not be <Build$Dir>.Export any
    more.
Admin:
  This change is required if <CExport$Dir> or <Hdr$Dir> do not exist
    when HdrSrc's export phase is executed.

Version 0.58. Tagged as 'HdrSrc-0_58'

Version 0.57. Tagged as 'HdrSrc-0_57'

Detail:
  ErrorBase_MediaCtrl added for Pace (arodger)
Admin:
  E-mail received 2 Nov 1999.

Version 0.56. Tagged as 'HdrSrc-0_56'

Detail:
  New filetype allocation for 3rd party.
Admin:
  E-mail received 31 October 1999.  Scary.

Version 0.55. Tagged as 'HdrSrc-0_55'

Changed Lazarus ROM timing to 8 cycles = 125ns (was 10 cycles = 156ns).

Version 0.54. Tagged as 'HdrSrc-0_54'

Detail:
  New filetype allocations for 3rd parties.
Admin:
  E-mail received 25 October 1999.

Version 0.53. Tagged as 'HdrSrc-0_53'

Removed conditional compilation from reassigned IOMD interrupt stuff. Both sets of allocations are now included, prefixed by IOMD_ and IOMDr_.

This complicates the Kernel, where it is fixed at compile time, but it should
simplify everthing else, which will handle both at run time.

Version 0.52. Tagged as 'HdrSrc-0_52'

New version of DevNos will need to be sent to Pineapple, I expect.
IRQ changes will probably have repercussions throughout the build.

Version 0.51. Tagged as 'HdrSrc-0_51'

Detail:
  Engineering Menu application's error block added.
Admin:
  Required by STB-400 Engineering Menu application.
  E-mail received from Pineapple on 22 October.

Version 0.50. Tagged as 'HdrSrc-0_50'

Detail:
  Changes are:
    New Wimp message.
Admin:
  E-mail received 20 Oct 1999.

Version 0.49. Tagged as 'HdrSrc-0_49'

Kernel instead of PS/2 support.

Version 0.48. Tagged as 'HdrSrc-0_48'

Detail:
  Changes are addition of error block, SWI chunk and device number
    for third-party.
Admin:
  E-mail received 14 Oct 1999.

Version 0.47. Tagged as 'HdrSrc-0_47'

Version 0.46. Tagged as 'HdrSrc-0_46'

Detail:
  Various source modules contain his header privately, and all have
    slightly differently commented versions, with or without
    assertions.  This was was voted best-in-class and promoted into
    the Macros file.
Admin:
  Tested briefly.


Version 0.45. Tagged as 'HdrSrc-0_45'

Version 0.44. Tagged as 'HdrSrc-0_44'

Version 0.43. Tagged as 'HdrSrc-0_43'

Version 0.42. Tagged as 'HdrSrc-0_42'

Lots of machiine definition changes for Lazarus. In particular, IO speed now divide by 2, so won't work on current bodged Model 1 hardware.

Version 0.41. Tagged as 'HdrSrc-0_41'

Detail:
  FSNumbers
  ISV-SWIs
  ISV-Types
  NewErrors
Admin:
  Received from Alan on 22nd September 1999.

Version 0.39. Tagged as 'HdrSrc-0_39'

Detail:
  Register/ISV-SWIs
  Register/ISV-Types
  Register/Keyboard
  Register/NewErrors
  Register/Pointer
  Register/Services
Admin:
  Added PS2Driver SWI chunk manually from information e-mailed me by Alan.
  Retained Kevin's Countries changes and mailed Alan updated master copy.

Version 0.38. Tagged as 'HdrSrc-0_38'

Modified Hdr:Machine.Machine for Lazarus - new flags "DontUseVCO" and
"PAL_Columns".

Version 0.37. Tagged as 'HdrSrc-0_37'

Fixed spelling mistake in Register/Messages.  'Message_IconizeAt' was spelt 'Message_IconiseAt' in the latest update from AMG.  AMG should be made aware of this error.

Version 0.36. Not tagged

Version 0.35. Tagged as 'HdrSrc-0_35'

Detail:

  No centralised keyboard definition file was available, so the file
  "Register.Keyboard" has been added.  This defines all keyboard type IDs,
  KeyV reason codes and flags words, and also includes definitions of
  the standard low-level key numbers.

  The assembler header file is processed by Hdr2H to produce the C version
  as expected.
  The new file "Register.Keyboard" has been despatched to Pineapple, since
  it will be centrally maintained under their allocation procedures.  (The
  file was sent on 25/08/99.)
Admin:

  Tested.  Verified that the C file is generated correctly.

Version 0.34. Tagged as 'HdrSrc-0_34'

Detail:
  The IOCtl calls used to be defined only within the DualSerial sources;
  no central (global) definitions were available.  The file "IOCtl.h" has
  been added to overcome this, defining IOCtl call reason and group codes,
  and declaring a structure "ioctl_t" used when using IOCtls via OS_Args.
  This is exported to "C.Global.h.IOCtl" by HdrSrc.
  At present, no assembler header file exists as it is unlikely
  to be required due to the majority of new source being written in C,
  although the file "IOCtl.h" could be auto-generated by Hdr2H from an
  assembler variant in the future if required.
  Also added support for StripDepnd into makefile.
Admin:
  Tested.


Version 0.33. Tagged as 'HdrSrc-0_33'

All required files are now re-instated.

Version 0.32. Tagged as 'HdrSrc-0_32'

  Added capability to export all ImageSize and Machine files.
Detail:
  Our local copies of The Pineapple-maintained master files are now
    maintained by CVS.  The Register directory holds all files
    controlled by Pineapple and must only be updated with imports from
    Pineapple.  All files inside Import directory have been removed.
    Moved several header files from hdr to Register directory to
    signify change control has passed to Pineapple.  This applies to:
    DevNos EnvNumbers, KEYV, Messages, PaletteV and Pointer.  New
    contents of Register directory are up-to-date masters from
    Pineapple as of Friday 20th August 1999.
  Added OPTIONS to the export target list.  If OPTIONS=ALL is
    specified on the make command, then all the Machine and ImageSize
    files will be exported.  This has been added primarily for the use
    of the BaseSW build process.
Admin:
  Tested.

Version 0.32. Tagged as 'HdrSrc-0_32'

Version 0.31. Tagged as 'HdrSrc-0_31'

Version 0.30. Tagged as 'HdrSrc-0_30'

Version 0.29. Tagged as 'HdrSrc-0_29'

Added new CMOS bit for Freeway to stop it assigning network 1 addresses to interfaces on initialisation.

Detail:
  New CMOS bit comes from spares in Acorn Access section - which overlays
    LanManFS/NFS boot mount path - but then again, so does everything else
    regarding ShareFS.
  New *Configure FreewayAutoAddress [on|off] *-command added.  CMOS default
    will enable the current behaviour, so it must be explicitly set to
    change behaviour.
Admin:
  Tested in Ursula ROM build - will not affect STB builds, as they do not
    contain Freeway (or will overwrite the address anyway).
  Required by Freeway 0.29

Version 0.28. Tagged as 'HdrSrc-0_28'

  More assembler files translated to C.
  CMOS header file modified slightly to enable Hdr2H to translate it.
Detail:
  Hdr2H has been removed - it's now in the library (v0.28 or later).
Admin:
  The extra header files have been checked for correctness.
  Requires Library 0.28 or later (RiscOS/Library  Tag: Library-0_28)
  C module which import the exported header files will require
    cmhg 5.25 or later (RiscOS/Library  Tag: Library-0_28 or later)

Version 0.27. Tagged as 'HdrSrc-0_27'
