* iface/gspn/gspn.cc: Adjust to newer g++.

intricate memory corruption bug prevented me to check the patch
in.  It took me two days to realize why find_state() must do a
double loop over the candidates to check for equality before
checking for inclusion(s).

* iface/gspn/ltlgspn.cc: New options, -e45 and -n.
* iface/gspn/ssp.cc, iface/gspn/ssp.hh: Handle these.
* src/tgbaalgos/gtec/gtec.cc (TRACE): Add some debugging traces.

(couvreur99_check_shy_ssp): Add a onepass_ attribute to
disable the "shyness", and do not increment pos before calling
find_state since gspn's implementation uses it.
* iface/gspn/ssp.cc: Enable "onepass_" for all "shy" variants,
and also fix find_state for the case where onepass_ is
disabled (but I do not yet know why the latter fix isn't enough).

Reorganize this function so that syntactically there is only one
loop over the successors, and not two.  Call reintroduce the call
to couvreur99_check_shy::state_index(), needed by SSP, and
suppress that to index_and_insert introduced on 2004-12-29.  Also
split the "group" option in two: "group" and "group2".  "group2"
is the equivalent of the older "group", while the new "group" is
weaker and faster.
