I don't know if there is any way to get them dumped to stdout, but certainly the
manpage for the SunCC compiler states:
Predefinitions:unix
sparc (SPARC)
i386 (x86)
sun
The above are not predefined in -Xc mode.
These predefinitions are valid in all modes:
__BUILTIN_VA_ARG_INCR
__SUNPRO_C=0x590
__SVR4(SPARC)
__SunOS(Solaris)
__amd64(x86 with-m64)
__gnu__linux(linux)
__i386(x86)
__linux(linux)
__linux__(linux)
__sparc(SPARC)
__sparcv9(with-m64)
__sun(Solaris)
__unix
__`uname -s`_`uname -r`(Solaris)
__x86_64(x86)
linux(x86,linux)
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.
