Perhaps if you would submit a patch to newlib, something may happen.
It's not difficult to back-port stand-alone from recent gcc if you don't
want to wait for cygwin to include a gcc upgrade, about which there have
been plenty of threads here.  You could include it in a <mathinline.h>
of your choice.

http://gcc.gnu.org/ml/gcc-patches/2005-03/msg01973.html
shows that it has been available for 2.5 years.  The x87 code quoted
there appears to be SSE3.
