2010-01-30 Thread Bill Hart
I found another Ultrasparc2 which is set up correctly (same linux), and the MPIR C++ tests pass no problems. So this confirms my belief that gcc54 was just set up wrongly. I'm going to close the longstanding ticket we have open for that, and I'll just build on the other machine I have found, in fu

I think this is known, but I can't remember whether it's been reported or not; certainly I have run across very similar behavior in the past as well. I think that some things related to this are because our fast evaluation routines do not know how to handle z.real() and friends, but that may be ch
