<DT><TT>--enable-multilib </TT>[default]
- <DD><P>This is part of the generic multilib support for building
- cross compilers. As such, targets like "powerpc-elf" will
- have libstdc++ built many different ways: "-msoft-float" and
- not, etc. A different libstdc++ will be built for each of the
- different multilib versions. This option is on by default.

libstdc++-v3 is used.) The --disable variant will put all std::
symbols into the global namespace.

<DT><TT>--enable-cshadow-headers </TT>
<DD><P>This turns on the code to construct shadowed C headers, and to
2.90.8, 'single' and 'posix' are the only implemented models.

- <DT><TT>--enable-libgcc-rebuild=DIR / --disable-libgcc-rebuild</TT>
- <DD><P>This is a grueling temporary hack no matter which way you look
- at it. It's described in <A HREF="gccrebuild.html">its own
- little page</A>. Note that other --enable flags will
- interact with this one. In libstdc++-v3 snapshot 2.90.8,
- this is enabled by default, with DIR set to
- <TT> '../..' </TT>, so that building the complete GCC sources
- with libstdc++-v3 in place works transparently. Since then,
- library sources have been merged into the compiler sources,
- and this option has been removed.

- For instance, the following puts all the libstdc++ headers into a directory called "2.97-20001008" instead of the usual "g++-v3"

flags to the compiler to use when building libstdc++. FLAGS
