[patch 1/1 v2] support AC_SUBST'able automake rules

[Lars J. Aas]

Something like this?

2001-02-09  Lars J. Aas  <address@hidden>

        * automake.in ($MACRO_PATTERN): Include '@' in name regex.
        (&canonicalize): New. Includes '@' in canonical range.
        (&check_canonical_spelling, &handle_programs, &handle_libraries,
        &handle_ltlibraries, &handle_techinfo): Use &canonicalize.
