             Bug #: 53155
           Summary: Not parallel: test for -j fails
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: marc.glisse@normalesup.org


Hello,

in order to decide whether they should run the testsuite in parallel, the
makefiles in gcc/ and libstdc++-v3/testsuite/ use the following test:

[ "$(filter -j, $(MFLAGS))" = "-j" ]

However, at least with the gnu make 3.81 shipped by debian, MFLAGS merges all
options, so it would normally be something like -wkj, which doesn't match the
filter.
