            Bug ID: 78880
           Summary: [7 Regression] Revision 243196 breaks bootstrap on
                    x86_64-w64-mingw32
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rainer@emrich-ebersheim.de
  Target Milestone: ---

Revision 243196 breaks native bootstrap on x86_64-w64-mingw32 using
--with-sysroot to point gcc to the mingw-w64 runtime. This used to work since
years until then.

The bootstrap fails in stage 1 building libgcc due to not finding the runtime
libraries:
