          * isprint() now true for non-breaking spaces
<math.h>  * FP_INFINITY corrected to FP_INFINITE
          * fma(), fmal(), llrint(), llrintf(), llrintl(),
            llround(), llroundf(), llroundl(),
            remquo(), remquof(), remquol() added.
          * added inlining for remainder() and fmaf() and various
            float functions.
          * math_errhandling removed pending overhaul - it was misleading.
          * expm1() and log1p() now provide decent (< 1 ulp) accuracy,
            rather than only being marginally better than exp(x)-1 and
            log(1+x).
          * new version of copysign() with standard calling conventions.
          * some C99 functions changed to use infinity/NaNs and exceptions
            for error handling - see comments in header file about the
            changes in progress.
<stdio.h>  * output from %a now correctly rounded
<stdlib.h> * strtof() and strtold() added.
<string.h> * strerror() no longer clears _kernel_last_oserror().

Version 5.49. Tagged as 'RISC_OSLib-5_49'

* _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'

  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'

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