  Well, I'm not familiar enough with fortran to know if the community already
figured out a response to the PR323 issue.

  What I did find out, amusingly enough, is that a number of the controversial
climate research centers use beowulf clusters based on Xeons or AMD64s, so if
they didn't use the right compiler flags to get SSE rather than x87 math....
who knows!
