           Summary: "--enable-maintainer-mode --disable-werror" wrongly
                    upgrades warnings to errors in libstdc++
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: John.Tytgat@aaug.net


Using gcc 4.6trunk r168215, target arm-unknown-eabi, newlib 1.19.0, binutils
2.21.

Configured with: --target=arm-unknown-eabi
--prefix=/home/joty/projects/gccsdk/riscos7/cross
--with-gmp=/home/joty/projects/gccsdk/gccsdk_svn7/gcc4/builddir/installed-libs-for-cross-gcc
--with-mpfr=/home/joty/projects/gccsdk/gccsdk_svn7/gcc4/builddir/installed-libs-for-cross-gcc
--with-mpc=/home/joty/projects/gccsdk/gccsdk_svn7/gcc4/builddir/installed-libs-for-cross-gcc
--with-ppl=/home/joty/projects/gccsdk/gccsdk_svn7/gcc4/builddir/installed-libs-for-cross-gcc

--with-cloog=/home/joty/projects/gccsdk/gccsdk_svn7/gcc4/builddir/installed-libs-for-cross-gcc
--disable-threads --disable-multilib --disable-shared --with-newlib
--enable-maintainer-mode --disable-werror --enable-interwork --disable-nls
--disable-libquadmath --enable-checking=release --enable-languages=c,c++

Mind "--enable-maintainer-mode --disable-werror" being used.

And this still results in a -Werror during libstdc++ building, which results
into:

--8<--

Removing --enable-maintainer-mode is of course a workaround but I expect that
with a --disable-werror this should not result in -Werror being used at all.

Fixed in trunk. Now --disable-werror removes -Werror from the build warning
flags, even in maintainer mode.
