error with autogen.sh probably related to gnulib update

[Patrice Dumas]

Hello,

When I run ./autogen.sh, it ends with


libtoolize: copying file 'gnulib/m4/lt~obsolete.m4'
autoreconf: configure.ac: not using Intltool
autoreconf: configure.ac: not using Gtkdoc
autoreconf: running: aclocal --force -I gnulib/m4
autoreconf: running: /usr/bin/autoconf --force
configure:16405: error: possibly undefined macro: gl_STDALIGN_H
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: error: /usr/bin/autoconf failed with exit status: 1


The issue is in tp/Texinfo/XS/configure where there is indeed that macro
unexpanded.  I have no good idea on what to do...
