The SUNWspro man page for cc(1) contains the following (entries for -xarch=v9
i.e. 64bit sparc apply in my case)

...
Predefinitions:unix
sparc (SPARC)
i386 (x86)
sun

The above are not predefined in -Xc mode.
These predefinitions are valid in all modes:
__sun
__unix
__SUNPRO_C=0x540
__`uname -s`_`uname -r`
__sparc (SPARC)
__sparcv9 (SPARC with -xarch=v9|v9a|v9b)
__i386 (x86)
__BUILTIN_VA_ARG_INCR
__SVR4
The following is predefined in -Xa and -Xt modes only:
__RESTRICT
The compiler also predefines the object-like macro
__PRAGMA_REDEFINE_EXTNAME,
to indicate the pragma will be recognized.
...

Guess the ___SUNPRO_C macro is a start. 'fraid the only other compiler I can
test against is gcc-3.4.1. Any suggestions, I'll give 'em a try.
