win32/include/math.h: rint/trunc: pop fp stack

... in order to avoid fp stack overflow (see test below).

#include <math.h>
#include <stdio.h>
int main()
{
   printf("%f %f %f %f\n", trunc(1.2), rint(1.2), trunc(1.2), rint(1.2));
   printf("%f %f %f %f\n", trunc(1.2), rint(1.2), trunc(1.2), rint(1.2));
   printf("%f %f %f %f\n", trunc(1.2), rint(1.2), trunc(1.2), rintl(1.2));
}

Also in rintl:
- 'long double' is not a ten-byte float on windows.
