            Bug ID: 58638
           Summary: libstdc++ builds as non-PIC when --with-pic is
                    specified
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: skunk at iskunk dot org
              Host: x86_64-unknown-linux-gnu
            Target: x86_64-unknown-linux-gnu
             Build: x86_64-unknown-linux-gnu

I built GCC 4.8.1 with "--disable-shared --with-pic" so that I can statically
link libgcc/libstdc++ into executables, including shared-library builds.
However, when I attempted to build a C++ shared object on Linux/amd64 using the
new compiler, I got this:

libtool: link: g++  -fPIC -DPIC -shared -nostdlib /usr/lib/../lib64/crti.o
/opt/tg-opt/gcc--4.8.1--linux64/bin/../lib/gcc/x86_64-unknown-linux-gnu/4.8.1/crtbeginS.o

relocation R_X86_64_32S against `a local symbol' can not be used when making a
shared object; recompile with -fPIC

collect2: error: ld returned 1 exit status

This is a regression from 4.7.x, when --with-pic correctly caused all (static)
runtime libraries to be built with PIC code.
