[Bug libfortran/30005] New: Open errors (not/already exists etc.): show also the file name

[burnus at gcc dot gnu dot org]

Example 1:
  open(77,file="not-existing.dat",status="old")
gfortran:
  At line 1 of file aaaa.f90
  Fortran runtime error: No such file or directory
ifort:
  forrtl: severe (29): file not found, unit 77, file /dev/shm/not-existing.dat
Expected: Add (similar to ifort) also the file name (and maybe the unit
number?) to the error message.

This should also be the case if no "file=" has been given, e.g.
  open(77,status="old")
ifort: file not found, unit 77, file /dev/shm/fort.77

Reasoning:
a) It is easier to see directly the needed file name than finding it in the
source code
b) The user might not have access to the source code


Example 2:
  open(77,file="already-existing.dat",status="new")
gfortran:
  At line 1 of file aaaa.f90
  Fortran runtime error: File exists
ifort:
  cannot overwrite existing file, unit 77, file /dev/shm/already-existing.dat
Expected: Add (similar to ifort) also the file name (and maybe the unit
number?) to the error message.

Preliminary patch

This patch adds a few checks for types of errors on opening a file to give a
more use friendly message.  I will probably put together a helper function in
error.c to do this in the final patch.

Mark as fixed. As enhancement it does not need to go into 4.2/4.1.
