yes, except that I do not run aclocal there.

gnulib CVS head does not contain gl_INCLUDED_REGEX.

the easiest way to reproduce the problem is
$ cvs -d:pserver:address@hidden:/cvsroot/clisp login
$ cvs -z3 -d:pserver:address@hidden:/cvsroot/clisp co -P clisp
$ cd clisp
$ make -f Makefile.devel check-configures

this will create configure.ac in the current directory and remove at
afterwards.
you might want to try the appended patch to keep configure.ac and also
th produce a log from "--verbose"
