[RFC] GCC-4 new packaging.

    Hi all,

  I'm about ready to release a new compiler package.  This is going to mean a
whole bunch of new packages and one obsoletion, and I was hoping I could get a
hand proof-reading the setup hints and any comments anyone has on packaging,
names and categories.

  First off, there's a whole bunch of new runtime libraries:

gcc4-libgcc1-runtime-4.3.2-2
./usr/bin/cyggcc_s-1.dll

gcc4-libgomp1-runtime-4.3.2-2
./usr/bin/cyggomp-1.dll

gcc4-libssp0-runtime-4.3.2-2
./usr/bin/cygssp-0.dll

gcc4-libgfortran3-runtime-4.3.2-2
./usr/bin/cyggfortran-3.dll

gcc4-libffi4-runtime-4.3.2-2
./usr/bin/cygffi-4.dll

gcc4-libgcj9-runtime-4.3.2-2
./usr/bin/cyggcj-9.dll
./usr/bin/cyggcj-tools-9.dll

gcc4-java-runtime-config-4.3.2-2
./etc/defaults/usr/lib/logging.properties
./etc/defaults/usr/lib/security/classpath.security
./etc/postinstall/gcc4-java-runtime-config.sh
./etc/preremove/gcc4-java-runtime-config.sh

gcc4-libobjc2-runtime-4.3.2-2
./usr/bin/cygobjc-2.dll

gcc4-libstdc++6-runtime-4.3.2-2
./usr/bin/cygstdc++-6.dll

gcc4-libgnat4.3-runtime-4.3.2-2
./usr/bin/cyggnarl-4.3.dll
./usr/bin/cyggnat-4.3.dll

  I considered breaking out the Java and GNAT DLLs into individual packages,
but figure they're liable to be so closely coupled that it would be pointless.
 I don't know if it's even worth having a separate package for the java config
files, but I did it anyway.

  Note also that there is no gcc4-runtime-4.3.2-2, which was the package that
contained the old unversioned cyggcc_s.dll we've been using so far.  In order
to obsolete it, can I just update the existing setup.hint to move it into the
_obsolete category, or does there need to be a version number change?

  Next are the main compiler packages.  I would be glad if anyone could cast
an eye over the list of package contents for me and sanity check that I
haven't put anything in obviously the wrong place.  Each one should contain
just the executables, headers, link libs and docs relevant to its language.

  Lastly, I've attached my hint files, and again, I could really use a hand
proof-reading and sanity checking, because there's so many of them I'm almost
bound to have made a cut and paste error that I've now looked at too many
times to be able to see.

  The things to look out for are did I get the sdesc right, is the category
right (Devel for all, also Libs for the runtimes), and do the requires lines
look like they're vaguely right or contain any obvious gaping omissions.

  Obviously nobody can verify they're actually right without having copies of
the DLLs themselves, but I used a script to collect the cygcheck output for
all the DLLs and executables in the packages and generated the attached
deps.txt file from it, so anyone who was feeling particularly keen could give
it another cross-check for me..... pretty please? ;-)

  So, barring last minute hitches, I should be able to upload this around the
end of the week.  I would welcome any comments or advice on the packaging,
because this is a major transition and I'd like to get it right and not
inconvenience any of the users.  Opinions welcome!

    cheers,
      DaveK
