Sage-4.0

See https://groups.google.com/group/sage-devel/browse_thread/thread/8cadd969aca13e64 for a discussion thread about the release.

In order of priority:

1. Pynac -- mhansen+burcin will have a patch soon
2. Solaris 10 -- about 7 remaining bugs for 32 bit Sparc and x86, some rather difficult. [to satisfy this goal, user will have to build custom toolchain, and we're only really going for this working on two specific machines on skynet]
3. Doctest 75% -- plan given below
4. OS X 64-bit -- doesn't start up due to libSingular issue, but after that, probably 5 tests [to satisfy this goal, it is only necessary that it is easy to build *binaries*, and it only has to support Intel. It's not necessary that any random user can just type "make" and have everything trivially work].
5. Remove deprecated quaddouble.spkg

Good idea to fix:

1. http://trac.sagemath.org/sage_trac/ticket/3984, and update to upstream version.

2. Update sage-vmware-4.0.zip so that it includes Ubuntu-8.04.LTS

gcc 4.4.0

I spend some time tonight on the gcc 4.4.0 porting problem and there
is only little work left to be done: I had resolved all issues in Sage
3.1.2, but neglected to merge all the fixed into subsequent releases.

Issues from 3.1.2 (3.4.2):

 * gmp (gone in MPIR)
 * ntl (Fixed in ntl-5.4.2.p7.spkg, need to add spkg-check before
posting spkg)
 * fplll (update to 3.0.11 - or maybe a future 3.0.12 due to bug that
already existed in 2.x.)
 * polybori - fixes:
    * src/boost_1_34_1.cropped/boost/mpl/aux_/full_lambda.hpp +230
    * src/boost_1_34_1.cropped/boost/mpl/apply.hpp +138
    * src/boost_1_34_1.cropped/boost/mpl/bind.hpp +364
    * src/boost_1_34_1.cropped/boost/mpl/bind.hpp +531
    * src/boost_1_34_1.cropped/boost/mpl/apply_wrap.hpp +81
    * src/boost_1_34_1.cropped/boost/mpl/apply_wrap.hpp +173
 * clisp - *boom* - might be build problem - will use ecl in
4.0.alpha0 anyway

The main issue I ran into was a bug in libfplll that would crash the
doctest with some probability. The bug is also in the previous fplll
release and I have send a proposed fix upstream, so I am confident we
will have gcc 4.4 support in Sage 4.0. At least two people have either
complained in IRC, so the demand seems to clearly exist. :)

Cheers,
