There has been a long standing bug which prevented Sage building on Solaris if the Sun compiler was installed.
http://trac.sagemath.org/sage_trac/ticket/6595 I'm not sure how well the Sage server is working or not, so I thought I'd attach this small patch. Could some kind people please test it? I've tested it on Solaris, so it does not really need much testing there, though of course, one can't really test things too much. But on other platforms it would be really helpful if it could be tested. If I've got it right, it should have no effect whatsoever to anyone unless your system falls into one of these two categories. 1) You use AIX, HP-UX, IRIX, Solaris or Tru64 2) You use Sun Studio on Linux. Both are quite rare, so hopefully it wont change anything for anyone else. It is a patch against the Sage library (in the sage-4.3.spkg in the directory c_lib).
