[Automake-NG] [PATCH 0/4] Prefer pattern rules over suffix rules

[Stefano Lattarini]

Pattern rules are cleaner, safer, and vouched for in the GNU make manual
itself.  Supporting them instead of suffix rules will also allow us to
simplify a little the automake script, auxiliary perl modules, and
documentation.
    
This change introduces a slight backward-incompatibility now, in that
user provided definitions of the SUFFIXES variable or of the .SUFFIXES
target, as well as old-fashioned suffix rules, are now rejected.
    
Automake-NG still tries to parse and understand suffix-based pattern
rules though, to retain support for user-added file extensions in the
_SOURCES variables (see "Handling new file extensions" in the Automake
manual).

As usual, I will push to 'ng/master' in 72 hours if there is no
review by then.

Regards,
  Stefano

Stefano Lattarini (4):
  [ng] am: prefer pattern rules over old-fashioned suffix rules
  [ng] rules: can pass deps to &Automake::Rule::define
  [ng] rules: forbid old-fashioned suffix rules, prefer pattern rules
  [ng] cleanup: &Automake::Variable::hook is unused, remove it
