This is important, because the system checks will yield different results depending on whether POSIX threads are enabled or not. We also use PTHREADS_CFLAGS only in ZTS mode now. Using these flags in non-ZTS mode causes complete build failures on some platforms (i.e. FreeBSD 2.2.x). This will cause harmless warnings on some platforms (i.e. Solaris 2).
