I am not too familiar with the c99 details, but if changing the flags is
actually the cure to your problem, here's what I'd do. The error message
looks like it's emitted by the preprocessor invocation which can be
tweaked with EXTRA_CPPFLAGS (EXTRA_CFLAGS is passed to the compiler
only). Using that should already give you better results. You can use
"mgar modenv" to verify the invocation flags without actually running
the build.

For how exactly to tweak the flags. Usually there's a good chance that
other people have already run into a similar problem and have solved it.
Try searching the existing build recipes for "99", maybe that gives you
the solution right away.
