If you have some developer power to spare, it may be worthwhile to try to
tackle this yourself. Otherwise I am afraid this will never be implemented in
GCC. The patch in comment #10 is very rough and outdated, but the idea is
simple. Copy diagnostic.c to diagnostic-xml.c and start modifying the output
functions to emit XML.

This will be trivial to do.

This will be more complicated, because the diagnostics machinery does not have
a concept of multiple messages belonging to the same diagnostic. But I think
this is eventually the way to go (and I think Gabriel, the diagnostics
maintainer, thinks the same) by the way of defining an internal representation
for diagnostics output. (http://gcc.gnu.org/ml/gcc/2012-04/msg00567.html)
Dumping this internal representation in XML format would be easy then.

But designing and implementing this IR does not seem trivial, so you may want
to start with the simple stuff.
