Comment (by albertstrasheim):

 Ok, I've done some more digging.

 If I make the following changes to the generated umathmodule.c it compiles
 with Python 2.6 and Visual Studio 2008 on Vista x64:

 {{{

  #endif

  #ifndef HAVE_FREXPF
 +#undef frexpf
  static float frexpf(float x, int * i)
  {
      return (float)frexp((double)(x), i);
  }
  #endif
  #ifndef HAVE_LDEXPF
 +#undef ldexpf
  static float ldexpf(float x, int i)
  {
      return (float)ldexp((double)(x), i);
 }}}

 So I suspect HAVE_FREXPF and HAVE_LDEXPF are not being defined when in
 fact they should be.

 Can't do the build with numscons yet, because of this bug:
