Don't forget to try building a simple testcase for the gcc failure ...

Start with the full GSXML.m file, then get gcc to preprocess it and give
you a fully preprocessed file (run gcc with -E).  Check that compiling the
preprocessed source still crashes the compiler.  Then, start removing code
from the preprocessed thing trying to keep the failure ... then removing
compiler flags etc if you can end up with a few lines of code which crash
the compiler, and submit it to GNATS, it will hopefully be fixed (or, you
can check that it has already been fixed on more recent GCCs)!  It's quite
long as a process, but might be rewarding :-)
