Thanks for reporting this.  This comes from the following change by
Claudio Fontana which was installed yesterday into gnulib:


combined with the fact that Bison does not have an intl/ subdirectory
and doesn't use AM_CPPFLAGS.

I'd rather not complicate all the Bison builds with an unused
-I../intl flag, so I installed this workaround to the Bison bootstrap
script, but I hope there's a better way in general.  Perhaps we need
to distinguish the 'gettext' module from the 'gettext-intl' module?

        * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
        that variable and the line breaks the bootstrap.  Problem reported
        by Juan M. Guerrero.
