David Schultz 8f3f7c66d0 Make sure that symbols are declared in math.h iff the appropriate ... namespaces are visible. Previously, math.h failed to hide some C99-, XSI-, and BSD-specific symbols in certain compilation environments. The referenced PR has a nice listing of the appropriate conditions for making symbols visible in math.h. The only non-stylistic difference between the patch in the PR and this commit is that I superfluously test for __BSD_VISIBLE in a few places to be more explicit about which symbols have historically been part of the FreeBSD environment.
