[GCC-XML] How to debug gccxml?

[Daniel J. Lauk]

Hi.

I ran into some trouble, why else would I want to debug? ;-)
My questions are:

1) How do I make a debug build of gccxml? (couldn't find appropriate CMake 
docs)
2) How would I run the gdb (or any GUI frontend) so that it breaks inside of 
xml.c:do_xml_output?

Regards,
DJ
