* Added two new library chunks, 4 and 5, which contain extensions to the kernel and C library respectively. These have no static data associated with them, just being extensions of the stub tables. The reason for this is to minimise wasted space in programs that don't use the C99 facilities; o.stubs is now a library split into 3 pieces - basic kernel and CLib, extra kernel and extra

  CLib; only the bits a program needs get included.

* Previous extensions to the C library stubs revoked - they now stop at _swix;
  all the new C99 functions now live in chunk 4. Anyone using those new
  functions should relink with new stubs and ensure this C library version.

* printf/scanf now support 64-bit types through "ll" and "j" length modifiers.

* Run-time support for VLAs (__rt_allocauto and __rt_freeauto) added. No
  attempt is currently made to clear up on longjmp or to cope with someone
  changing the kernel allocator while a VLA is active. These would be a
  future enhancement.

* Added complete 64-bit run-ti...

  * snprintf(), vsnprintf(), vfscanf(), vscanf(), vsscanf()
  * hh, j, z and t printf length modifiers (indicating char, intmax_t, size_t
    and ptrdiff_t respectively)
  * Hexadecimal floating-point printing and scanning (%a/%A)
  * %F printf() specifier (upper-case form of %F)
  * Input/output of NaNs and Infinities
  * imaxdiv_t, imaxdiv(), strtoimax(), strtoumax() (simulated through macros)
  * <fenv.h>: feclearexcept(), fegetexceptflag(), feraiseexcept(),
              fesetexceptflag(), fetestexcept(), fegetround(), fesetround(),
              fegetenv(), feholdexcept(), fesetenv(), feupdateenv()
  * FLT_EVAL_METHOD, DECIMAL_DIG
  * hypot(), hypotf(), fabsf(), fdim(), fdimf(), fmax(), fmaxf(), fmin(),
    fminf()
  * INFINITY, NAN, fpclassify(), isfinite(), isinf(), isnan(), isnormal(),
    signbit(), copysign(), copysignf(), nan(), nanf(), nextafter(),
    nextafterf() isgreater(), isgreaterequal(), isless(), islessequal(),
    islessgreater(), isunordered()

This...

  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'

  Another getenv() bug fixed.
Detail:
  stdio.c contains a vastly improved implementation of fwrite.
  hostsys.h declares _terminate_getenv to remove build warnings.
  armsys.c contains fix to getenv() to stop Omni dying.
Admin:
  Tested on desktop machine for over a week without incident, including
    several heavy fwrite users (WebServe, C compiler)
  fwrite change is documented in Doc/fwrite
  getenv() bug is Bugzilla bug #28

Version 5.27. Tagged as 'RISC_OSLib-5_27'

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

Version 5.15. Tagged as 'RISC_OSLib-5_15'

  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.

Version 4.90. Tagged as 'RISC_OSLib-4_90'

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'

Merged Spinner branch changes onto trunk (new RCA messages files and Makefile changes). Convert to srccommit while we're at it.

Removed a few $Revision's to prevent future spurious merge clashes.

Version 4.87. Tagged as 'RISC_OSLib-4_87'
