New description:
The aim is to add a gcc package to Sage. We probably don't want to always
build it, we would install it by default only on systems where this is
needed. This would replace the fortran package.
'''spkg''':
[http://boxen.math.washington.edu/home/jdemeyer/spkg/gcc-4.6.3.spkg]
'''Apply''':
1. [attachment:12369_gcc_root.patch] to the `SAGE_ROOT` repository.
2. [attachment:12369_scripts_hgignore.patch] to the `SCRIPTS` repository.
3. [attachment:12369_doc.patch] to the Sage library.
'''Testing releases''':
1. GCC-4.6.3:
[http://boxen.math.washington.edu/home/jdemeyer/release/sage-5.0.beta7-gcc/]
2. Dependencies only:
[http://boxen.math.washington.edu/home/jdemeyer/release/sage-5.0.beta7-gccdeps/]:
this contains all ''dependencies'' of this ticket but not this ticket
itself, it still includes the old Fortran spkg.
Neither of these releases contain a fixed ATLAS (#12011), as that's work
in progress.
For systems other than OS X, installing the "gccdeps" distribution is
equivalent to installing the "gcc" distribution with
`SAGE_INSTALL_GCC=no`. On OS X, the "gcc" distribution normally will not
build with `SAGE_INSTALL_GCC=no` because Fortran is missing.

Comment:
I believe this is '''ready for review''' now. I don't know of any
regressions, in the following sense: for every system on which vanilla
sage-5.0.beta7 works, also sage-5.0.beta7-gccdeps and sage-5.0.beta7-gcc
work.
It even builds and passes all tests on OS X 10.7, but there is still a
serious issue with ATLAS (#12011, causing a failure in the `cvxopt` test
suite). But I don't believe that should prevent a review of this ticket,
as it's unrelated to GCC.
