In general, option b has much better c++ results than a).  The c++
test results are essentially identical to those with 3.2.  However,
compared to the results that I have been posting for 3.2, we have
the following new failures:

gcc.c-torture/execute/ieee/rbug.c

g77.f-torture/execute/19990313-[0-3].f

20_util/allocator_members.cc execution test
22_locale/codecvt_members_char_char.cc execution test
22_locale/codecvt_members_wchar_t_char.cc execution test
22_locale/ctor_copy_dtor.cc execution test
22_locale/ctype_members_wchar_t.cc execution test
27_io/ostream_inserter_arith.cc execution test

It would probably be useful to compare test results for b and c.  It may
be that some of the above are glibc or system problems.  I am fairly
certain c will build on all platforms.  However, I know that there is
one c regression under hppa near the beginning of march.  There is another
at the beginning of May.

As a matter of release philosophy, I don't much like hybrids.  Option
b adds another permutation to maintain even if the new c++ capabilities
are very tempting.  My focus will be 3.2.  3.1 will only get small bug
fixes.  If we keep to the main releases, it much easier to verify and
resolve bugs.

So, I would say use a as the default.  This is the conservative choice
and well tested across a broad range of systems.  Option a can easily be
used to build c.  Maybe you could include c as well for experimental
development and building c++ packages that need the dw2 support under
parisc-linux.
