What do you think of this:

Use glibc feenableexcept to set the control word if present, or

failing this, on x86 only (possibly amd64, is it identical in this
respect?), set the control word with inline assembler, or

failing this, provide no support.

The second should catch both windows and modern mac.  The ppc mac and
sparc solaris would be orphaned.

Might I obtain some access through you?
