Building the 'gnumakefile' module fails: http://autobuild.josefsson.org/gnulib-mega/log-201206201113065857000.txt
Looking at that module, I wonder if that module is useful at all without maintainer-makefile? It seems GNUmakefile is tightly coupled together with maint.mk. Should GNUmakefile be moved into the maintainer-makefile module, and the gnumakefile module be removed? /Simon
