[Jack Jansen] I need a little guidance with bug #775892. I think it's non-serious, but I'm not sure (and I don't know how easy it is to fix).

Testcoercion is failing on the beta for MacOSX 10.3. All the failures have the same form: the output is (XXX-0j) in stead of the expected (XXX+0j). It isn't serious, and we've (you & I) been thru this failure before . If the compiler for this box has some sort of switch named along the lines of "don't used fused multiply-add", it should cure it. Ah... Long ago in a universe far from here... I remember, I had the same problem on MacOS9 at some point. But the strange thing with the current incarnation of the problem is that the exact same binary (build on OSX 10.2) passes testcoercion on 10.2 but fails it on 10.3. Could the C library be involved?

Or the compiler. Is Panther using the same gcc 3.3 as the last dev tools update?
