    rules: prefer pattern rules over old-fashioned suffix rules
    
    Not only pattern rules are cleaner, safer, and vouched for in the GNU
    make manual itself, but they will also allow us to obtain substantial
    simplifications in the automake script, auxiliary perl modules, and
    documentation.
    
    This introduces a slight backward-incompatibility now, in that user-provided
    definitions of the 'SUFFIXES' variable are now rejected.
    
    * lib/am/footer.am: Declare '.SUFFIXES:' with empty dependencies, to
    neutralize the default suffix rules.
    * automake.in (&handle_footer): Reject the 'SUFFIXES' variable.  Don't
    process its content anymore.  Don't generate the .SUFFIXES special target
    anymore.
    (&register_language): Don't bother registering the suffix rules anymore.
    This should be OK, since all the relevant '.am' fragments (e.g., yacc.am
    or depend2.am) now use pattern rules, not suffix rules.
    (&var_SUFFIXES_trigger): Remove.  And don't install it as an hook for the
    now-deprecated 'SUFFIXES' variable.
    (handle_single_transform): Don't try to "correct" the source extension
    by taking into account possible suffix rules; this was done ...
    (derive_suffix): ... with this variable, that has thus been removed.
    * lib/Automake/Rule.pm (&define): Don't process old-fashioned suffix rules
    specially, but just reject them.
    (&register_suffix_rule, &suffix_rules_count, &suffixes, @_suffixes,
    $suffix_rules, $_suffix_rules_default): Delete.
    (@EXPORT): Adjust.
    ($_SUFFIX_RULE_PATTERN): Made local to the '&define' function.
    * t/ext3.sh: Remove as obsolete.
    * t/suffix-rules-reject.sh: New test.
    * t/txinfo6: Adjust.
    * t/parallel-tests8.sh: Likewise.
    * t/warnings-strictness-interactions.sh: Likewise.
    * t/warnings-win-over-strictness.sh: Likewise.
    * t/warnings-precedence.sh: Likewise.
    * t/warnings-override.sh: Likewise.
    * t/warning-groups-win-over-strictness.sh: Likewise.
    * t/amopts-variable-expansion.sh: Likewise.
    * t/specflg10.sh: Adjust. XXX XXX XXX

    am: prefer pattern rules over old-fashioned suffix rules
    
    The use of pattern rules is cleaner, safer, and vouched for in the
    GNU make manual itself.  Moreover, it will allow us to obtain some
    simplifications in the automake script and the documentation in
    future changes.
    
    * lib/am/texinfos.am: Turn this suffix rules into pattern rules.
    * lib/am/texibuild.am: Likewise.
    * lib/am/depend2.am: Likewise.
    * lib/am/yacc.am: Likewise.
    * lib/am/lex.am: Likewise.
    * lib/am/lang-compile.am: Likewise.  Also, since we are at it, remove
    extra blank lines and quote 'like this' rather than `like this'.
    * t/ext.sh: Adjust.
    * t/objc-basic.sh: Likewise.
    * t/objcxx-basic.sh: Likewise.
    * t/suffix.sh: Likewise.
    * t/suffix2.sh: Likewise.  Also, define a dummy LIBTOOL in Makefile.am
    instead of requiring the libtool macros.
    * t/cxx.sh: Remove as obsolete.
    * t/nodep.sh: Likewise.
