Add a fix for working fesetenv in libquadmath-library
fesetenv was broken and do not sets new fpu state because it's now
overwrites new env state by fnstenv.
And this patch must fix it by store only mxcsr and load its afterwards:
diff --git
Fesetenv does not change fpu rounding mode. This bug already described
in https://sourceforge.net/p/mingw-w64/bugs/541/
