The 6th part [wstate] of our patch series (thirdround) is a slightly
improved version of
http://gcc.gnu.org/ml/gcc-patches/2010-09/msg01150.html by adding
comments notably taking into account Laurynas remarks in
http://gcc.gnu.org/ml/gcc-patches/2010-09/msg01151.html &
http://gcc.gnu.org/ml/gcc-patches/2010-09/msg01153.html

#################### gcc/ChangeLog entry relative to patch piece 5 [typedopt]
2010-09-21  Jeremie Salvucci  <jeremie.salvucci@free.fr>
	    Basile Starynkevitch  <basile@starynkevitch.net>

	* gengtype-state.c: Added new file.

	* gengtype.c:
	(type_count): New static variable.
	(new_structure, find_structure, find_param_structure)
	(create_pointer, create_array): Use type_count for initializing
	state_number field of types.
	(main): Initialize state_number in predefined types.  Call
	read_state and write_state appropriately.  Show the
	type_count when verbose.

	* gengtype.h: Updated comment about per-language directories.
	(read_state, write_state): New declarations.

	* Makefile.in (MOSTLYCLEANFILES): Added gtype.state.
	(GENGTYPE_FLAGS): New variable.
	(s-gtype): Runs gengtype twice, once to write the gtype.state,
	once to read it.
	(build/gengtype-state.o): New target.
	(build/gengtype): Use it.
	(mostlyclean): Remove gtype.state

Also, how should the gengtype program be installed? Perhaps it should
be named gcc-gengtype?  I still need help on these minor issues, in
particular as ways to patch gcc/Makefile.in.... There has been some
discussions & suggestions, but I was not able to imagine a
gcc/Makefile.in patch from them.  I confess that I don't understand all
of gcc/Makefile.in in particular the installations tricks. 

I am as usual attaching the cumulated patch w.r.t. trunk 164437.

Ok for trunk?

Cheers.
