            Bug ID: 86399
           Summary: gcc 9.0 from r262251 can't be build for
                    Windows/mingw-w64 target
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mateuszb at poczta dot onet.pl
  Target Milestone: ---

In r262251 it was changed file "gcc/coverage.c":
+#if HAVE_DOS_BASED_FILE_SYSTEM
+         const char separator = "\\";
+#else
+         const char *separator = "/";
+#endif

For Windows/mingw-w64 target it should be *separator instead of separator,
tested patch:
--- gcc/coverage.c      (revision 262370)
