Ah, yes; maintainer-clean only works if you have run 'make check' before
(and no 'make clean' in between), so that all the old test subdirs have
a Makefile.  Same thing with distclean.

Thanks.  The .gitignore issue is obvious, I've pushed that; the
old-m4-iface.m4 change should be obsolete with the pending patch.
I'll deal with the ltmain.m4sh change when we're through with this.

Thanks; fixed like this, and put you in THANKS.

Cheers,

        Skip sys_lib_search_path on systems without libz.
        * tests/search-path.at (sys_lib_search_path): Autotest needs at
        least one AT_CHECK executed in a test group.  So if we haven't
        found -lz anywhere, as may happen with cross-compilers, skip the
        test.
        * THANKS: Update.
