* _Exit() added.
* Lots of new <math.h> functions (acosh, asinh, atanh, exp2, expm1,
  ilogb, log1p, log2, logb, scalbn, scalbln, cbrt, erf, erfc,
  lgamma, tgamma, nexttoward, fmaf). Float and long double forms
  of every function added; long double forms are included as another
  library object in the stubs rather than the shared library, as they
  just branch to the double form.
* Subnormal/NaN/infinity cases in various <math.h> functions improved.
* Added <tgmath.h>.
* Headers brought into line with CC 5.54.
* RMEnsures added to C library initialisation to try to load minimum
  CallASWI, FPEmulator, CLib. No errors reported if load fails.
* A few pointless inter-file dependencies removed to reduce minimum
  size of included ANSILib.

Version 5.46. Tagged as 'RISC_OSLib-5_46'

Detail:
  strxfrm was passing the buffers to the Territory module SWI the wrong
    way around so Territory_TransformString copied the destination over
    the source rather than vice versa!
Admin:
  Reported by <mailto:ian.foster@gps.tandb.co.uk>
  Fixes Bugzilla bug #4375


Version 5.33. Tagged as 'RISC_OSLib-5_33'

  Initialised so_far in stdio.c to remove compiler warning.
Admin:
  Built.  strcmptest() still indicates that strcmp() is working OK!

Version 5.32. Tagged as 'RISC_OSLib-5_32'

Detail:
  This alternate implementation returned non-zero for equal strings,
    because the tidyup routine failed to stop examining the differing
    words when it found matching zero bytes.
Admin:
  Tested in softload C library, and in Lazarus ROM image.  strcmp()
    appears to be working per spec now.

Version 5.31. Tagged as 'RISC_OSLib-5_31'

  Fix for RISC_OSLib res() function.
Detail:
  Version 4.89 featured an improved strcmp() routine that didn't actually
    work properly (bug #4085).  The return values had the wrong sign if this
    optimised code was used and the string contained top-bit set chars.
  Removed that rlib.s.asmdefs hack as the comment in the makefile suggested.
    Nothing needs it any more as the assembler sources that require it now
    get via a -PD argument.
  res_ prefix function was still wrong as it failed to detect valid but wrong
    filenames, hence the "Make$Path not defined" errors in the latest tools
    release.
Admin:
  Fixes Bugzilla bug #4085
  Should fix BaseSW's build problems too.

Version 5.29. Tagged as 'RISC_OSLib-5_29'

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

Version 5.15. Tagged as 'RISC_OSLib-5_15'

Detail:
  Somebody had modified the SWI call to Territory_Collate to be done
    via _swix instead of _kernel_swi, but didn't remove the _kernel_swi_regs
    variable (r) and didn't change the function return value to return the
    new "ret" variable instead of r.r[0] which gives arbitrary results - in
    particular it confuses qsort.
Admin:
  Tested that it builds.

Version 4.97. Tagged as 'RISC_OSLib-4_97'

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