I've recently tried a GNU-style build of gdb and discovered
that I had to change gdb/Makefile.in to turn off the MMALLOC
support because the mmalloc sources are not there.  So...

What is the best way to fix this?

1: Check in a copy of mmalloc
   (+) would allow normal GNU-style builds
   (-) mmalloc is not used on NetBSD-style builds,
       so it represents some (362K?) code bloat.

2: Change our gdb/Makefile.in to turn off MMALLOC?
   (+) then we don't need the mmalloc sources
   (-) local modification to Makefile.in not suitable
       for submission back to the maintainers.

I favor option 1.  Opinions?
