This isn't really a gcc issue, as gcc does not supply or implement
fpu_control.h.

I imagine that it would be possible to implement it on cygwin.  That
would be a topic to take up on the cygwin mailing list; see
http://cygwin.com/ .

I'm not sure there is any reasonable approach which would work on mingw,
but I don't know too much about that platform.  Here again you would do
better to ask on a mingw specific list.
