there's guint64 and gint64, but these types are not present on all
supported platforms (i can't say off hand which ones don't implement these
types, but every gcc-capable system and windows define G_HAVE_GINT64 and
therefore implement gint64 and guint64).

there are typedefs for gdouble and gfloat as well, they simply correlate to
the normal float and double types in C. we even used to have a gldouble, but
since that involved portability problems, this part is currently just disabled
in glib.h:

/* HAVE_LONG_DOUBLE doesn't work correctly on all platforms.
 * Since gldouble isn't used anywhere, just disable it for now */

#if 0
#ifdef HAVE_LONG_DOUBLE
typedef long double gldouble;
#else /* HAVE_LONG_DOUBLE */
typedef double gldouble;
#endif /* HAVE_LONG_DOUBLE */
#endif /* 0 */

(i guess "long double" is featured by gcc only).
