setting gcc42 as default compiler

Hi,

As 7-CURRENT is going to ship with gcc42,
I'd like to switch the default compiler for OOo ports to
gcc42, too.

General
* depending on gcc-ooo which is specific/patched version is
evil.
also useless for other than ooo2 ports.
* some people might also use gfortran as well, in this case
we install
gcc42 too and no additional compilers are needed.
* facilitation for gcc part of Makefile. we do not need to
consider about
gcc-ooo (i386) and gcc41 part(amd64/gcj build), but single
gcc42 part
is enough.

For 7-CURRENT
* No additional compiler will be needed for both FreeBSD
i386/amd64.

For 6-STABLE
* Just moving to one single compiler gcc42 is enough.

Drawbacks
* Sometimes we need additional gcc42 patches for OOo.

Issues
* gcc42-withgcjawt conflicts with gcc42 :( but I have an
idea...

Currently just i wrote this proposal.
Any suggestions/comments are extremely appreciated.

All the best,

Are you planning to fix compilation with gcj as part of this
commit? It 
has been broken for some time now. While I haven't had the
time to do a 
test run with the most recent port yet, I don't expect the
problems to 
have miraculously gone away:

I'll remove this knob from openoffice.org-2-devel port soon.

This sounds like a great plan!

The good thing here is that GCC 4.2 is still actively
maintained
upstream, and several Linux distributions are using GCC 4.1
(and
possibly 4.2) without specific changes.

You are welcome, and thanks for maintaining a lot of gcc
ports, too.
Now gcc42 is the default compiler for
openoffice.org-2-devel. So openoffice.org-2 (2.3) will be
build with
gcc42.

Extra qualification is now error by syntax strictness of
gcc4.2 and 4.1.
Thus we require some additional patches. But I beileve cost
I must
pay is not big as the maintainers of OOo in other GNU/Linux
distro. 
are also interested in this issue, so it will be fixed by
them very quickly.
