Yes, with this patch I can compile Git with GCC while the Perl module
gets built with Sun CC.  The result even works.

If the git commands written in Perl will be converted to use Git.pm,
Sun CC will become a new dependency for Git on Solaris, unless
people build a separate Perl with GCC or manually edit the generated
Makefile in the perl subdir to build the module with GCC.

Well, GCC comes along with Solaris on the CDs while Sun CC is a
separate product.  And usually it's easier to build free software
with GCC, because many projects use GCC extensions.  Often GCC is
the only compiler installed on Solaris machines.

Until the patch series from Florian Forster removed a lot of GCC'isms
a few days ago it was not possible to build Git with Sun CC.

Yesterday I could build the next branch with Sun CC 5.8 with a few
trivial changes.  I will send four patches in reply to this mail.

Junio, please consider the first two patches for inclusion into the
next branch.  The third patch is on top of Pasky's changes in the pu
branch.  The fourth patch is a strange workaround for a strange
problem of which I think it is an error in Sun's compiler.  That one
should not make its way into Git, but maybe someone on the list has
an idea about the problem.
