Sage4.0
See https://groups.google.com/group/sagedevel/browse_thread/thread/8cadd969aca13e64 for a discussion thread about the release.
In order of priority:
 Pynac  mhansen+burcin will have a patch soon
 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]
 Doctest 75%  plan given below
 OS X 64bit  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].
 Remove deprecated quaddouble.spkg
Good idea to fix:
http://trac.sagemath.org/sage_trac/ticket/3984, and update to upstream version.
 Update sagevmware4.0.zip so that it includes Ubuntu8.04.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.
