Uniform the style and eliminate a warning on newer doxygen version..

Some pthreads symbols might be present in libc (as shown on various *BSD)
but not all of them, leading to false positives.

Check for the most common compiler flags before the plain symbol check
to avoid known pitfalls.

There are alternate implementations of those libraries that use pthreads.

This long-deprecated code should disappear at the next version bump.

This enables a more C99-compliant implementation of printf et al.

The MinGW32 project is deprecating its old version macros.

The flag is not unconditionally added to CFLAGS either and the
programs built on the host do not get habitually fed to a debugger.
