    nobase_include_HEADERS = sig/functor.hxx sig/sigslot.hxx

    SUFFIXES = .m4

    sig/functor.hxx: sig/functor.hxx.m4
        m4 $(srcdir)/sig/functor.hxx.m4 > sig/functor.m4

    [ also for sigslot.hxx ]

This isn't perfect since you must arrange for mkdir sig somehow.
Automake doesn't do this automatically in this situation.

    CLEANFILES = $(nobase_include_HEADERS)

Marc>    - How to tell that the *.hxx are derieved from the *.m4?

As above.

Suffix rules don't work if the files are in subdirs.
Suffix rule support in automake could use some enhancements.

Not that I know of.
