I have an autotools project with no C in. I still want to use gnulib's maintainer-makefile module, but I don't want to use C. If I leave "lib" in the top-level SUBDIRS, then I'm forced to us AC_PROG_CC, or C source is (correctly: dummy.c) detected, and make fails, because I didn't set up a C compiler.
Hence the message telling me to put "lib" in SUBDIRS should either only be output if I actually have some C, or should be qualified by "(if you're using C)". -- http://rrt.sc3d.org
