GCC used to define a macro __STRICT_ANSI__ when `-ansi' was given on
the command line. The current version does not do this, which breaks
detection of whether `long long' is allowed. (For some reason this is
not hit in -current builds, but I have made some fixes to <stdlib.h>
which trigger it in every program which sets WARNS.)
Rather than trying to deduce whether `long long' is supported from
other macros, I simply modified the compiler driver to tell us. (BTW,
the `-posix' flag is utterly useless and should go.) If anyone has a
better way to accomplish this, I'm all ears.
(I suspect that the removal of __STRICT_ANSI__ was intentional, since
it's not clear what that should mean in the face of multiple C
language standards. The trouble is that C89 (implied by `-ansi') is
otherwise indistinguishable from C89+GCC-extensions (implied by the
absence of `-ansi'), and we need to make both cases work properly.)
