BTW ... so far as I can find, there is no attempt anywhere in the
Postgres sources to set either of these macros. And my understanding of
their purpose is that *system* headers should not be setting them at
all, rather the application sets them to indicate which POSIX feature
level it would like. So perhaps the real question here is where the
heck are your conflicting values coming from ...
