How do I put this. The apple fenv.h supplied functions "work" by only setting
bits in mxcsr (not cw), and then only setting bits 1-6. Problem is that the
actual working bits are in 7-12 (as in fpu-387.h). So my little test.f runs
with the default mask (all bits on). I get the failure when using gfortran as
the mxcsr bits
are all set off (same test.f as above, default compilation)
0x37f is cw
0 is cw_sse
Floating point exception
defalt cw_sse is 0x1f80 .
