           Summary: [gcc-4.6.0] opt.adb compiled error while multilib
                    enabled
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: ray_l...@hotmail.com


I am using MinGW (GCC-4.5.2 i686-pc-mingw32) to compiled a 64bit ada from
GCC-4.6.0。 the configure command is as following:

mkdir gcc-build
cd gcc-build
../gcc-4.6.0/configure --target=x86_64-w64-mingw32 --enable-targets=all
--enable-multilib --enable-64bit --prefix=/mingw32 --with-sysroot=/mingw32
--disable-shared --enable-static --enable-version-specific-runtime-libs
--with-dwarf2 --enable-fully-dynamic-string --enable-languages=c,ada
--disable-libgomp --enable-libada

then:

make all-gcc && make install-gcc  ---- sucesss, no problem.

make all-target-libgcc && make install-target-libgcc ---sucess, lib32 and lib64
installed.

make all-target-libada && make install-target-libada --- sucess, lib32 and
lib64 installed

but when i running make all-gnattools , the compile stop with the following
error:

I am not familiar with ada, could someone help me to check this problem. 

if any logs is needed just let me know.
