Patch for definition of NULL

[Mark Murnane <Mark Murnane Sun COM>]

Hi,

When compiling glib with Sun's Forte compiler, we run across problems
with the definition of NULL.  On Solaris systems NULL is defined as
either 0 or 0L, depending on whether or not you're compiling 64-bit
binaries.  I've put a conditional define in gmacros.h which only applied
when Forte is being used.  Does anyone have any objections if I commit
this?

Thanks,

Mark
