Hi! A few years ago we were reported that Bison’s install-pdf target fails because po/’s Makefile does not support it:
http://lists.gnu.org/archive/html/bug-bison/2012-04/msg00011.html Paul installed a workaround in gnulib itself (commit 88b94265b630cfcec39dafe954affcee03e36f72), but in f2f698092426d2fcb69beb184d92d177adc328bf (2015), an update from gettext to gnulib removed that. As a consequence, we have the very same bug report back in Bison (http://lists.gnu.org/archive/html/bug-bison/2018-06/msg00000.html). Could 88b94265b630cfcec39dafe954affcee03e36f72 be cherry-picked in both gnulib and gettext? Thanks!
