Hello,
Some users building GDB on systems where msgfmt is not available were
blocked when the build failed (in bfd, and probably another subdir
that I can't remember). See
http://sources.redhat.com/ml/gdb/2003-02/msg00310.html.
Instead of adding the checks in each subdir, I thought that it might be
better to do the check for msgfmt in the toplevel configure, and pass
--disable-nls to the subdir configure commands if not found. The
following patches tries to do this, and has been tested on a hpux box
where msgfmt is missing, and on a linux machine where msgfmt was
available.
Ideally, we want to do the check for msgfmt only if --disable-nls was
not already specified. However, the only consequence of not checking
for the presence of --disable-nls is that we might have more than one
--disable/enable-nls switches on the subdir configure commands. I
think it will be ok, since I've placed the --disable-nls at the end
so it should overide the user's switch. An AC_MSG_WARN may also have
been nice, but I decided against it because seeing a warning even
when the user has specified --disable-nls would seem strange...
Would the following change be acceptable for inclusion?

* configure.in: Add check for msgfmt, configure subdirs with
--disable-nls if not found.
* configure: Regenerate.
