Removed #if checks for crazy old versions of OS X.

The <arpa/nameser_compat.h> was introduced way back in OS X Panther, which
itself was end-of-lifed back in 2007. We can assume that any OS X machine
we build on will need that header file :-)

Why bother removing it? The flag we're checking (__APPLE_CC__) is actually
Apple's build number. Self-compiled versions of GCC (such as installing the
latest version of GCC from homebrew) sets the value to 0, making it useless
for this sort of compile flaggery.

Add development flag to disable the inline API.

A GCC bug[1] can, in some cases, pop up an unsuppressible pedwarn when
using a static inline standard library function from a non-static
inline function.

This normally doesn't show up, but can occur if you're running an
upgrade version of GCC (such as GCC 4.8 on OS X, which normally runs
GCC 4.2).
