[Patch, Fortran] PR 35033 - Fix ASSIGNMENT(=) checks

[Dominique Dhumieres]

Tobias,

I have applied your patch along with several others and i have
a regression:

FAIL: gfortran.dg/where_operator_assign_3.f90  -O  (test for excess errors)

on i686-apple-darwin9. Although I cannot rule out that the regression is
not due to the other patches, the reason of the failure:

/opt/gcc/_gcc_clean/gcc/testsuite/gfortran.dg/where_operator_assign_3.f90:14.43:

    module procedure a_to_a, c_to_a, a_to_c
                                          1
Error: Assignment operator interface at (1) must not redefine an INTRINSIC type assignment
/opt/gcc/_gcc_clean/gcc/testsuite/gfortran.dg/where_operator_assign_3.f90:57.12:

  use global
           1
Fatal Error: Can't open module file 'global.mod' for reading at (1): No such file or directory

seems related to your patch.

I don't know if the problem is with the patch or with a nonstandard conforming test.

Cheers

Dominique
