I did some search in the internet, and it seems that `-pedantic' is
only a problem before gcc 4.6, since later versions can disable
`-Wlong-long' with the pragma as defined already in the FreeType code.
For example, I get zero warnings in a non-devel build with gcc 4.7.2.

I'll now implement switching off `-pedantic' for gcc < 4.6 – since
`-pedantic' is mainly a diagnostic option, always enabled in the
`devel' build CFLAGS, this should be a safe route.

Maybe you find a different, better solution later :-)
