The identifier sun is not set if the compiler is in -Xc mode. It
would be safer to use to use __sun which is defined in all compiler
modes. The symbols defined in all modes are __sun, __unix,
__SUNPRO_C=0x500 (or 400, 420, etc.), __`uname -s`_`uname -r`
(e.g. __SunOS_5_8), __sparc (SPARC), __sparcv9 (SPARC with
-xarch=v9|v9a), __i386 (x86), __BUILTIN_VA_ARG_INCR, __SVR4.

That applies to the native compiler. Perhaps someone else could
establish what Solaris specific defines are available in gcc.
