Yes.  __STDC_VERSION__ is defined as 199901L.  See for example:
<http://lists.debian.org/debian-mentors/2002/10/msg00216.html>

Currently freetype has things like:

#if FT_SIZEOF_INT == (32 / FT_CHAR_BIT)

  typedef signed int      FT_Int32;
  typedef unsigned int    FT_UInt32;

#elif FT_SIZEOF_LONG == (32 / FT_CHAR_BIT)

  typedef signed long     FT_Int32;
  typedef unsigned long   FT_UInt32;

#else
#error "no 32bit type found -- please check your configuration files"
#endif

In C99 this could simply be:

  typedef int32_t     FT_Int32;
  typedef uint32_t    FT_UInt32;

No size testing required.  No problems with cross compilation nor
universal binaries.
