The fix is not needed with the !SunStudio compiler. I can compile a test
program that uses {{{_Complex_I}}} with the Sun compiler without resorting
to any hacks - see the big table above I produced.

In any case, I've not done much testing with !SunStudio on this, so it
would be unwise to start applying patches without testing them.

sun_complex.h hack;

Yes, I think so too. gcc 4.5.0 creates a file with the fixed header, which
I inspected. That is huge, looking similar to that the current patch in
Sage. There's no need to repeat them all. And as I noted before, it is
doubtful if its 100% legal to do so. All I did was copied the necessary
parts.
I did email the cvxopt developers about this, so hopefully it can be fixed
upstream. You might not actually need the patch at all when 1.13 is
released.
