That's pretty ingenious. Indeed, that works, since the include order
when compiling GDB files is the gdb directory, ahead of all other
dependencies. I'll send a patch shortly after having tested it.

That would be nice :-). I wanted to have a look, but m4/stdint.m4
needs a little bit of study time before I can understand it all...
