I forgot to check with the CVS, I was looking at 6-R branch, which still doesn't have Bruce's fix (I guess I should have posted my question to -stable instead). Any time table for a merge? I looked at the latest msun/amd64, there was no assembly version for rint(). Since C99 is not supported everywhere (4.x systems, e.g.), I still have to use rint() for portability. Does anyone plan to write a piece of assembly code for rint() on amd64? Besides the bug, the C version is noticeably slower. -lq
