Using fpu_control.h on mingw/cygwin

[Yinon Ehrlich]

Hi,

The Gnulib manual states that fpu_control.h is missing for various platforms, including 
mingw and cygwin 
(http://www.gnu.org/software/hello/manual/gnulib/fpu_005fcontrol_002eh.html#fpu_005fcontrol_002eh).

After looking into fpu_control.h it seems that there is no way to work around this 
limitation, since __fpu_control will not be defined on these platforms.

Is this right, or there is a workaround to use fpu_control.h by windows ?

Thanks in advance,
	Yinon
