Avoid `long long' warnings with older gcc compilers.
Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for versions < 4.6. This is especially needed for Max OS X since this OS runs a gcc variant (or emulation) based on version 4.2.1.
