On some systems pthread_mutexattr_settype() and PTHREAD_MUTEX_RECURSIVE are
not available by default.
Either _XOPEN_SOURCE or _POSIX_C_SOURCE needs to be set to to the right level
before including any system include file in order to have them exposed.
Fixes the following compile error:

With Microsoft Visual C++, we cannot use pthreads (MinGW sports an
emulation library which is the reason we did not need Windows-specific
hacks earlier). Happily, it is very easy to provide Windows-specific
emulations for the pthread calls we use.

In Microsoft's Visual C runtime, the snprintf() function is actually
called _snprintf. Let's just #define the former to call the latter.

This change is technically not required to support MSVC, but it was
detected by Microsoft's compiler.
