            Bug ID: 108899
           Summary: [13 Regression] ERROR: can't rename to
                    "saved-unsupported": command already exists on i386
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: haochen.jiang at intel dot com
  Target Milestone: ---

We currently got these errors on i386 when running tests.

ERROR: can't rename to "saved-unsupported": command already exists
ERROR: in testcase
/export/gnu/import/git/gcc-test-master-intel64-native/src-master/gcc/testsuite/g++.dg/modules/modules.exp

I checked the trunk and I suppose it is probably caused by
r13-6288-g5344482c4d3ae0618fa8f5ed38f8309db43fdb82.

This commit changed modules.exp and rename unsupported to saved-unsupported.

Feel free to correct me if I am wrong.
