--- Comment #13 from Rainer Emrich <rainer@emrich-ebersheim.de> ---
The proposed patch indeed fixes the issue on x86_64-w64-mingw32, libgfortran
builds again.

The results of a complete testsuite run can be found here:
https://gcc.gnu.org/ml/gcc-testresults/2017-01/msg01881.html

Comparing the fortran results to an earlier run yields:

1704,1707c1727,1729
< # of expected passes          43782
< # of unexpected failures      266
< # of expected failures                89
< # of unresolved testcases     1

> # of expected passes          44069
> # of unexpected failures      267
> # of expected failures                92

IMHO that's fine.
