            Bug ID: 100460
           Summary: [11/12 Regression] mingw build broken due to use of
                    unsupported open() flags
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: daniel.f.starke at freenet dot de
  Target Milestone: ---

GCC 11.1.0 fails to build with C++ under MinGW due to unsupported open() fl=
ags
S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH|S_IWOTH in function
finish_module_processing() within gcc/cp/module.cc.
I suggest to remove these flags.
MinGW will not fix this due to unforseen side effects:
