Bootstrapping issue finally resolved

[Paul Hilfinger]

Back in August, I reported a problem with bootstrapping Bison from the
CVS repository (appended below).  I didn't have any urgent reason to
resolve the problem, so it has languished, but FYI I have finally
resolved the issue.  It had to do with my installation of automake.
Because the Bison maintainers update the autoconf/automake versions
that they use far more frequently than anyone else on earth (:->), I
have to maintain my own local versions of these tools.  Unfortunately,
my usual method of package installation, where I create a separate
subdirectory for each installation, with some symbolic links to it
from a one bin directory, didn't work with these tools.  Specfically,
aclocal (in automake) looks for .m4 files in the directory under which
it is installed, and was therefore not finding the .m4 files
associated with gettext (also locally installed on my system, but in a
separate installation subdirectory).

Thanks to all who suggested fixes.  While it turns out that there was
a problem with my (g)m4 (actually, autom4te) installation, it was not,
in fact, the culprit in this case.
