And Bruno already voiced his objections, so I guess I will have to
live will that.  It's not a big deal to edit with Sed the few files
that refer to c++defs.h, as part of the config.bat run.  Of course, if
Bruno will change his mind, it will be even better.

I'm okay with renaming them to use underscores.  But if gnulib
maintainers object, the djtar utility will take care of these, too.
Editing Makefile.in to refer to them in config.h should not be a big
issue.

Life has its surprises.  I found some free time to work on support for
bidirectional editing in Emacs, and as a side effect, I could invest
some of that time into reviving the DOS build.

Of course, it is enough to rename only 2 of the 3, to avoid file-name
clashes.  So if your suggestion to rename gnulib-common.m4 and
gnulib-comp.m4 is accepted, that would solve the problem entirely.

Thanks!
