This sounds useful.  I don't think that the GPL license should be a big
deal because GDB macros are not linked against C code.  It seems like a
clear case of "mere aggregation" to me.

Would you like to submit a patch to add these to the tree?  Ideally, you
could add some documentation as well (probably adding what you put in
the commit message to the tree).
