            Bug ID: 96306
           Summary: gcn libgomp build broken after "libomp: Add
                    omp_depend_kind to omp_lib.{f90,h}"
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: openacc, openmp
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tschwinge at gcc dot gnu.org
                CC: ams at gcc dot gnu.org, burnus at gcc dot gnu.org,
                    jakub at gcc dot gnu.org, jules at gcc dot gnu.org
  Target Milestone: ---
            Target: gcn

After commit 2631d95ae29dc6a0f5bda4af1f6595a17b1efbfd "libomp: Add
omp_depend_kind to omp_lib.{f90,h}":

    configure: error: unsupported system, cannot find Fortran int kind=16,
needed for omp_depend_kind
    Makefile:15426: recipe for target 'configure-target-libgomp' failed
    make[1]: *** [configure-target-libgomp] Error 1

Is this another instance of the "'TImode' problem" indicated in PR95730 'GCN
offloading ICEs after commit fe7ebef7fe4f9acb79658ed9db0749b07efc3105 "Add
support for __builtin_bswap128"', or is it something else?
