Look for LongCommandLine flag, command line size currently
set at 1k.
For HAL/32bit builds, the kernel buffer space is at high
(top bit set) address, which may break some code using signed
comparisons. So *beware* that there may be some latent
bugs in old kernel code using these buffers, not yet found.
One such bug, in s.Arthur2 found and fixed.
Tested moderately on ARM9 desktop build.
Lovely to reimplement things I did two and half years ago.

Version 5.35, 4.79.2.37. Tagged as 'Kernel-5_35-4_79_2_37'

* Added ARM_IMB and ARM_IMBRange SWIs as recommended by ARMv5.
* Some early prototype HAL bits popped in - a lot of source restructuring still
  to come.
* New debug target creates an AIF image with debug information, and translates
  this into an ASCII object file for the 16702B logic analyser.

Version 5.35, 4.79.2.1. Tagged as 'Kernel-5_35-4_79_2_1'

Detail:
  "Podule" number now displayed again in *ROMModule output - flag
     preservation issue caused it to disappear in 5.23.
  *Eval output no longer misses its trailing space, neither do "Podule" or
    "Extn ROM" in *ROMModules output.
  Heap manager now works again in non-SVC modes.
  Exception dump now contains faked up 26-bit PC+PSR lookalike.
Admin:
  Assembled.

Details:
  The Kernel will now compile to produce a pure 32-bit system if No26bitCode is
  set to TRUE.
  If No26bitCode is FALSE, then the Kernel will be a standard 26-bit Kernel,
  although some internal changes have taken place to minimise compile
  switches between the two cases. See Docs.32bit for more technical info.

  The hardest part was the flood-fill...

Other changes:
  Pointer shape changes now take place on the next VSync, rather than actually
  WAITING for the VSync. Turning the Hourglass on shouldn't slow your machine
  down by 5% now :)

  Lots of really crusty pre-IOMD code removed.

Admin:
  Tested in 32 and 26-bit forms in a limited desktop build. Basically, this
  will need to see a lot of use to iron out difficulties. I'd like anyone who
  has a non-frozen project to at least attempt using this Kernel.

Version 5.23. Tagged as 'Kernel-5_23'

Detail:
  The code for *ROMModules uses OS_PrettyPrint, which seems unconcerned
    by such trivial things as leading spaces, which accounts for the
    misaligned output.  The code now starts by using ASCII 31 (hard
    space for OS_PrettyPrint's purposes) as the leading indent character
    to avoid confusion.
Admin:
  Tested on desktop build in both command-line and TaskWindows.

Version 5.20. Tagged as 'Kernel-5_20'

Bandwidth limit for 7500FE fixed.
RO371Timings flag set to :LNOT:STB

Version 4.64. Tagged as 'Kernel-4_64'
