  Aborts now give standard error messages (Abort on Data Transfer at... etc)
  *ShowRegs now filled in after aborts
  assert(), abort(), "free failed" and standard signal handlers now use Wimp
    error boxes if in the desktop
  Postmortem button on error boxes to view the postmortem

Also, x$multiply, x$divide, __rt_sdiv, x$remainder, x$udivide, __rt_udiv and
x$uremainder optimised.

Version 5.35. Tagged as 'RISC_OSLib-5_35'

Detail:
  * One check for 26-bit mode wan't being made, leading to the runtime reporting
    'Uncaught trap:' when a trap should have been catching the abort.  This
    prevented signal handlers from trapping some aborts.
  * When an abort was occuring in SVC mode, the stack wasn't being flattened,
    resulting in all sorts of nasty things when you tried to carry on from a
    signal handler (probably the main reason why you ever see 'No stack for trap
    handler'). SVC and undefined stacks are now flattened.  Further work should
    be done to restore the state of the OS after an abort, but this probably
    requires a new OS call to tidy itself up adequately.
Admin:
  Built 26-bit versions of the library with new 32-bit compatible entry points and checked abort handling with both sharedclibrary and ansilib.

Version 5.22. Tagged as 'RISC_OSLib-5_22'

Second attempt at getting 32-bit overlay manager to work.

Version 5.21. Tagged as 'RISC_OSLib-5_21'

Detail:
  This code would only work in 26-bit modes, since it stored the output
    flags using STR pc, [sp, #4*4]!.  When {CONFIG} is 32, it stores the
    CPSR instead.
Admin:
  Tested in 32-bit Lazarus build - this fixes the RCMMDriver stiffing
    (because it sits with interrupts off waiting for the C flag to be
    set on exit from an OS_Byte call it calls through _swix)

Version 5.19. Tagged as 'RISC_OSLib-5_19'

Detail:
  _kernel_setenv(varname, NULL) should delete the variables.  It now does.
Admin:
  Tested in module.

Version 5.18. Tagged as 'RISC_OSLib-5_18'

* Correction to static base location in modulewrap - was affecting some
  DSL 4000 video software.

Version 5.15. Tagged as 'RISC_OSLib-5_15'

OS_ReadSysInfo 6.

Version 5.08. Tagged as 'RISC_OSLib-5_08'

Version 5.07. Tagged as 'RISC_OSLib-5_07'

Version 5.06. Tagged as 'RISC_OSLib-5_06'

ROM patches.
fp and lr are now set correctly before calling a SWI. This allows much better
recovery if the SWI aborts or generates an error.

Version 4.95. Tagged as 'RISC_OSLib-4_95'

StrongARMfudge flag removed.
StrongARM compatibility set according to AMBKernel flag in Hdr:RISCOS
strftime %U and %W specifiers fixed for week 0.

Version 4.89. Tagged as 'RISC_OSLib-4_89'
