Update debugging GCC flags to use C99 rather than C89.  The driver for this change is the Mac OS X header libkern/OSAtomic.h, which exports "inline" functions and errors out under "-ansi -peduntic", causing an undesirable fallback to pthread-based atomic emulation under the atomics patch I'm about to submit.
