What are the built-in defines put into gcc to discriminate parts of
code intended for Solaris descent from other OSes ?
ntfs-3g uses legacy #ifdef's based on __sun __SVR4 and __SOLARIS__,
which ones are being defined by gcc (at least those intended for userland).
More generally which defines are meaningful to discriminate parts of code
against Linux, OpenBSD, etc. but not discriminate Solaris flavors, compilers
(Sun, gcc) or hardware (X86, sparc) ?
