You must have accidently used the system compiler, because gdb has a
testsuite for dwarf2 macros that fails if i compile it with your patch
turned on.
It's a very tricky to tell gdb what compiler to use for it's testsuite.

Yes, i should have added that.
You'll note the current scheme is to simply output an explicit end_file
for the macro info in dwarf2out_finish.

If you want to find the right place to output an end_file, and remove
that, that would be fine.

True enough.
