what does "fixes warnings" mean?  does it change the compiler's
behaviour, or does it just make sure stuff are defined in the right

how is this different from just a plain (and truly portable)
#define _XOPEN_SOURCE?

(the only concern I see here is that people on Linux platforms
might start churning out code that depends on certain gcc-only
features, without noticing...)
