No.
Only on those where GCC is available (for example, not on DEC ULTRIX),
and then only for when using GCC instead of the vendor compiler to
build, for example on Minix 3 where there’s ACK and GCC (the latter
being the less preferable one, as on HP-UX, Solaris, AIX, etc. where
the vendor compiler rocks).
But for GCC platforms, yes, you can. Note that the definitions are
not even consistent across gcc versions sometimes.
