C99/GCC extensions?

Hi all,

I was reading up on my Linux kernel development lore, and I just
learned about C99 and GCC-specific extensions to ANSI C. Does AbiWord
use these, or are they a no-no for portability? (I.e., do we support
MSVC, etc.?) I was especially wondering about branch annotation,
which would be very useful for the FV_View::_draw code I rewrote.
