I meant to add there are no compilers able to build Sage on Solaris on and
of the Skynet machines.

it builds on Solaris.
We should get that patch upstream if possible. As you can see, it is very
trivial. All we need to add to the upstream source is something like this.
{{{
#include <complex.h>
#if defined(__sun__) && defined(__GNUC__)
#if __GNUC__ < 4 || ( __GNUC__ == 4 && __GNUC_MINOR__ < 5 )
#undef _Complex_I
#define _Complex_I (__extension__ 1.0iF)
#undef I
#define I _Complex_I
#endif
#endif
}}}
There's no need to have a huge great header file as there is at the
minute. It is totally unnecessary. One two items are missing from the
header file, so only two need to be added. The patch currently add a very
large proprietary header file when only a few lines of code are needed.
