If I understand the situation/intent correctly, if gtk requires -lm,
that need is insulated from users of gtk, who can just link -lgtk+-2.0
(or whatever the thing's actually called) without needing to insert
-lm themselves, so pkg-config --libs won't contain any extra libs.
However, this means also that if the users need -lm for their own
purposes they can't rely on gtk bringing it in for them.
Again, IIUC. And who knows what happens with static libs...
