Problem 2 reported in Bug 42950 also occurs on mingw32, the others (1, 3-6)
not.

(2) /dev/null test (gfortran.dg/dev_null.F90 and gfortran.dg/write_to_null.F90)
where seemingly

#if defined  _WIN32
#define DEV_NULL "nul"

does not work as one gets:
  Fortran runtime error: File '/dev/null' does not exist
