>Description:
	The declaration of __flt_rounds() in i386/include/float.h is
	not within __BEGIN_DECLS and __END_DECLS.  This breaks C++
	programs which try to call __flt_rounds, since they look for
	__flt_rounds__Fv instead.

>How-To-Repeat:
	Include float.h from a C++ program and try to call
	__flt_rounds().
