Thanks for the reminder! I even regtested with a test case - but I 
forget to include it in the patch ...

Committed attached patch as Rev. 170521. I will backport after 
regtesting the branches.

Tobias

PS: Maybe I should again use "svn" where "svn add" simply works; in 
"git" one always starts staging files; one then needs to revert the 
staging, if one does not want to commit them ...

The testcase has

use omp_lib

and failed:

/export/gnu/import/svn/gcc-test-ia32corei7/src-trunk/gcc/testsuite/gfortran.dg/gomp/task-1.f90:10.14:^M
^M
   use omp_lib^M
              1^M
Fatal Error: Can't open module file 'omp_lib.mod' for reading at (1): No such
file or directory^M
compiler exited with status 1

Shouldn't this testcase be in libgomp?
