True enough; I was able to come up with this similar patch without too
much effort, all without looking at yours.  I don't have OS/2 available,
so please test this patch out on your system against the latest on
branch-1_4 in CVS (I tested it on cygwin, which also cares about EXEEXT,
but is more forgiving of omissions and isn't really impacted by OBJEXT).
If it works for you, I will go ahead and commit this version, and you
won't have to worry about the paperwork delay (you can still fill out an
assignment, though, if you want easier acceptance of future patches).

Right now, I have to use an ASCII transcription of your name in ChangeLog,
per GNU coding standards; but I will use your preferred spelling in THANKS
(patch to THANKS not listed here, since it includes lots of email
addresses).  Also, I will be committing THANKS in utf-8 encoding, rather
than Latin1, since that seems to be what other packages have been doing.

2006-05-09  Eric Blake  <address@hidden>

        Portability updates for OS/2.
        * THANKS: Update.
        * src/Makefile.in (EXEEXT, OBJEXT): Define.
        (LINK): Use CFLAGS.
        (.c.obj): Define.
        * lib/Makefile.in (OBJEXT): Define.
        (.c.obj): Define.
        * doc/Makefile.in (install, uninstall): Install info files into
        the dir listing.
