More non-Linux build updates, mostly Darwin

Darwin's binary format does support symbols with differing visibilities, but
it does not support the protected or internal visibilities- only hidden. For
Darwin only, we should fall back to this visibility to prevent warnings from
the compiler and because it is close enough for our library purposes.

See http://gcc.gnu.org/viewcvs/*checkout*/trunk/gcc/config/darwin.c, search
for the "darwin_assemble_visibility" function for more details.

Also add pacman.static.exe to gitignore.
