Thanks, Bjørn; -ipo no longer breaks compilation (I didn’t specify it, but I
see that it was getting added automatically). I was really hoping that
"-fp-model precise” (which also implies -prec-div which would seem to affect
the other option mentioned) would have an impact on “make check” here, but
apparently not. Also -wd188 is no longer required to hide warnings; this
doesn’t seem to be happening anymore (but remember it myself from earlier on).
I guess it might make sense to check with Intel; we have support. I wish I
could remember if this ever worked right, but I don’t think I thought/knew to
run "make check" on our older builds.
