Personally, I don't like very much the idea of fiddling wit= h the x87
status and control bits for implementing the fe* functions.  I think we should _read_ those bits and put them into the values those
function return, but we should not _write_ the bits.

In other words, feraiseexcept should add bits to some word it
maintains internally, but not in the x87 status word.


But, that's precisely what _control87() does -- it sets the bits in the stat= us word.  The fact that the fe* functions exist doesn't imply that a us= er has to use them any more than does the existence of the _*87() functions.= --part1_7b.1cd667f3.2ceb6b21_boundary--
