This involves adding 36 new entries to the stubs. Current versions of the C
library will not fault client programs with such larger stubs, but will fill
in the extra entries with junk. Programs requiring the new functions will have
to RMEnsure this version of the Shared C Library.

This version of the C library has been fixed so that in future, any extra
unknown stubs entries will be filled in with a branch to zero, rather than
corrupted.

Requires cc 5.41 or later, both to build, and to make use of some of the extra
facilities.


Version 5.37. Tagged as 'RISC_OSLib-5_37'

  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'

  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.
