           Summary: Crosscompiler to ia64-hp-vms: vmsdbgout.c:368:20:
                    error: ISO C++17 does not allow 'register' storage
                    class specifier [-Werror=register]
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jbglaw@lug-owl.de
  Target Milestone: ---

I'm revamping my testing efforts, building cross compilers based on targets
listed in ./contrib/config-list.mk.

With .../configure --target=ia64-hp-vms --enable-werror-always
--enable-languages=all --prefix=/tmp/gcc-ia64-hp-vms (using g++ (Debian

compiler), build breaks (as of ed16241c6db23013d70b792a64f29080ad48a414) with
this (cf. http://toolchain.lug-owl.de:8080/jobs/gcc-ia64-hp-vms/8):
