By default -- yes, it is going to build with base gcc. But topic and, therefore, my reaction was about overriding compiler to be lang/gcc* from ports and whether there are ports, which fail in that case. At least, as I understand it. Now, why overriding the compiler for Glib seems important to me and why I tried to do that: Since commit aba0f0c38bbfa11ad48b5410ebdbed2a99e68c58 Author: Ryan Lortie <de...@desrt.ca> Date: Tue Oct 18 16:21:50 2011 -0400 gatomic: introduce G_ATOMIC_LOCK_FREE glib atomics implementation depends on gcc predefined macro __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4, which is absent on the base gcc-4.2 and on Clang (all version, at least at that time). As consequence, we have a mutex-based implementation of atomics. Building Glib using more modern GCC (e.g. gcc-4.7) would help, but gnome-libtool hack prevents us from that.
