            Bug ID: 79322
           Summary: gcc-6.3.0 inconsistent libstdc++ and libgcc_s link for
                    libcc1 and libgcj
           Product: gcc
           Version: 6.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: edeveaud at pasteur dot fr
  Target Milestone: ---

building and installing gcc-6.3.0 on non std directory lead to some libstdc++
link mismatch.

most of the libraries are linked to gcc-6.3.0 installed libraries
while some other are linked to system libraries


libcc1.so is linked to 
   -> /usr/lib64/libstdc++.so.6 instead of $PREFIX/lib64/libstdc++.so.6
      /lib64/libgcc_s.so.1      instead of $PREFIX/lib64/libgcc_s.so.1

libgcj.so libgcj_bc.so libitm.so libstdc++.so are linked to 
   -> /lib64/libgcc_s.so.       instead of $PREFIX/lib64/libgcc_s.so.1
