If you compare the generated aclocal.m4 file in the buggy situation and in
the working situation, you will see this difference:

In other words, 'aclocal' had decided to not include warn-on-use.m4
because it found the gl_WARN_ON_USE_PREPARE macro already defined in
gnulib-common.m4.
The fix is to hide this definition from 'aclocal'. I'm applying this fix.
Not pretty, but it works.
