Detail:
  s.makehswis used to pull in various IO header files. There was no good
  reason for this, and doing so causes a dependency upon Hdr:Machine.<Machine>
  to define which generation of IOC/IOMD is in use - which is a problem if
  the C library is to be built where Machine=All.
Admin:
  Tested in a Machine=All build.

Version 5.54. Not tagged

Detail:
 This changes all the C and assembler includes to be a canoncial Unix format.
 Also match include paths to previous commit for EditIntern/DrawIntern/VerIntern
 Finally, also include some minor type fixes (NULL vs 0)
Admin:
 May be some other paths elsewhere in the source I'm not immediately able to fix.  Will address any issues ASAP, since this is a huge change.

Version 5.54. Not tagged

Detail:
  * No longer uses aasm to build h.swis.
  * (Only) compatible with new C compilers: assumes const static data is
    placed in separate read-only areas, and suitable command-line switch
    is used to ensure that library static data is never placed in a zero-
    init area.
  * Stack extension code now thread-safe.
  * Heap thread-safety code (in clib) now uses SWP instruction test results
    from stack extension code (in kernel) - as a side effect, the exported
    symbol _swp_available now exists, if you need to use it elsewhere.
  * Slightly closer to having top-bit-set heap addresses working.
Admin:
  Tested in a Tungsten build, and with Customer W's test suite.

Version 5.48. Tagged as 'RISC_OSLib-5_48'

Detail:
  New script will search the export directory for headers that should
    be exported SWI symbols for it and only cause them to be included
    if it finds the header file.  This means that unless a component
    in your build actually needs the SWI symbols from another component,
    you no longer require that component to be in your modules file
    purely to enable successful generation of swis.h
Admin:
  Test build performed.

Version 5.03. Tagged as 'RISC_OSLib-5_03'

Detail:
  The Makefile now performs a diff of CLIB:h.swis and derived.swis
    in order to determine whether it needs to export the header or
    not.  This can save compilation time if the header file has not
    changed since it used to cause virtually all C code to recompile.
  s/makeswish now imports Hdr:Machine.<Machine> and executes $GetIO
    to ensure that the Portable module header export functions
    correctly.
Admin:
  Tested.

Version 4.98. Tagged as 'RISC_OSLib-4_98'

  Moved template for swis.h out of asm source into separate text file.
Detail:
  s.makehswis: The text which forms the common header for the derived
    swis.h is now stored externally rather than declared inline with
    assembler directives.
  h.swisheaders: The external file containing the common header.
    Now wraps the declarations of _swi and _swix with "#pragma -v4"
    to activate the _swi/_swix parameter checking for those functions.
  Makefile: Added dependency of derived.swis on h.swisheader
Admin:
  Built and exported.  Tested with cc 5.09 and it was happy with the
  new pragma (it ignores it).  Tested with what will be cc 5.10 and
  it recognised it and started checking _swi and _swix calls.
