the state_is_accepting() method for tgba_sba_proxies, or by
looking at the first outgoing transition of the state.  Pass
the result to the dectorator.

available while computing the emptiness check.

removing one useless loop, creating many duplicate transitions
that had to be merged.

* examples/cmilner/Makefile.am (cmilner_LDADD): Link with -lm, to
find the pow() function.

* src/tgba/tgbaexplicit.cc (tgba_explicit::compute_support_conditions):
Fix logic.  This function has always been returning bddtrue instead
of the actual computed value...

* wrap/python/tests/run.in, iface/nips/nipstest/defs.in,
iface/gspn/defs.in: Do not disable VERBOSE when running from "make
check".  Since we have started using parallel-check on 2009-08-31,
we should always send verbose output to the log.

* src/tgbatest/kv.test, iface/nips/nipstest/dotty.test: Don't rely
on the ${DOT-...} syntax, because DOT is always set and might be
set to the empty value.

access to that host.

* src/tgbatest/kv.test: Use ${DOT-true} instead of ${DOT-:}.  I
don't know, the MacOS shell must be mixing the syntaxes for
${DOT:-} and ${DOT-:}.

So far all neverclaims encountered would use (!(x)), but the
files from the Büchi store do not.

* src/neverparse/neverclaimscan.ll: Accept ! in front of guard,
so that we can read Promela files from Goal's Büchi store.
* src/tgbatest/neverclaimread.test: Test it.

from Goal, to ease the use of formulas provided by the Goal team.

safe side.
