[GCC-XML]gcc-xml in the build process (make)

Thanks :)

This is correct.  You can add -fxml=foo.xml and get the XML output during
complilation.

This is also correct, using the same flag as above.  Often the
meta-information will be mostly correct even if errors occur during
compilation.

Definately.  Separate runs means separate parsing steps.  The XML dump
requires almost no time in comparison to the other steps.

One day...maybe.  Soon...unfortunately, no.  If it becomes more widely
used, something similar may eventually be accepted by the GCC folks.  
Currently I have no official connection with them.  Also, the tool is
mostly tuned for use with CABLE (http://public.kitware.com/Cable) to
generate Tcl wrappers for C++ classes.  It has yet to be used for much
more than that, and thus the XML may be missing information that you might
need (like function bodies).

Thanks for your interest,
