Since I updated to Windows 10 and a clean install of Python xy on my 64Bit Windows 10 machine, I cannot compile f2py modules anymore.
F2py finds the gfortran compiler and apparently mingw32, but all efforts end up in errors and eventually ends up in error code 1:

Here is the information from -c --help-fcompiler: Fortran compilers found: --fcompiler=gnu95 GNU Fortran 95 compiler (4.5.2)
On my old Python server the same fortran code compiles into a PYD which is usable, but not in my new environment. As the FORTRAN compiler can be found, the error has to be somewhere else. Any ideas?
