Well, that's annoying. :-)

I looked into the problem some more and found what I think is the 
underlying problem: gnulib-tool generated lib/gnulib.mk.in before it 
generates m4/gnulib-comp.m4, which Makefile-generation relies upon. I 
reverted my recent hack to emacs/admin/merge-gnulib and installed the 
attached Gnulib patch. Please update to the latest Emacs and Gnulib and 
try again.
