DJGPP needs support for the COFF debug info because the DJGPP port of
Emacs can only be built with -gcoff.  That's because no one ported
unexec.c in Emacs to DWARF-2 debug info embedded in COFF binary
format.  I don't expect such changes in unexec.c any time soon.

OK, I will run at least some of them.
