I don't have time today to look into this further, but it looks like it is because the code that checks the CFLAGS is trying to use the previous CFLAG checking attempt. Below is from my FreeBSD box that is having the same problem as the OS X buildbot: it doesn't actually try -Warray-bounds until it gets to the next check (-Wformat-security), then you see -Warray-bounds in the gcc line. This is from config.log and it makes the GTK+ check program fail using -Warray-bounds, which my gcc doesn't support.
