             Bug #: 53523
           Summary: i686 compiler with multilib ( x86_64 target ) included
                    fails on linker
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org

Simple Shell containing the commands I used ran.

I was trying to build a compiler where the default output is i686 ( 32-bit),
but the compiler can handle building 64-bit libraries. This occurs when trying
to link the  libgcc_s.a (64-bit version )


Attached is a simple text file outlining all of the commands I ran.

Sorry, I build multilib using 4.7.x branch successful on linux.
I took a closer look to your build-script - what I normally don't do, but I was
curious to learn what issue you might have - and noticed that you aren't using
a prefix, which is a bit unusual.  Nevertheless I see that you missed to enable
64-bit bfd for binutils, which will end in not supporting x64 pe-coff.  Please
take a closer look to mingw-w64's Wiki and about how to built multilib.
