Unfortunately, it needs more work.  CVS m4 branch-1_4 now fails with:

 cd .. && /bin/sh /home/eblake/m4/missing --run automake-1.10a --gnu 
configure:15119: error: possibly undefined macro: gl_STRING_MODULE_INDICATOR
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
make: *** [../configure] Error 1

Contrary to the Changelog entry, I don't see gl_STRING_MODULE_INDICATOR defined 
in string_h.m4.
