[Bug target/18106] New: Weak symbols are unimplemented on Windows

[aaronavay62 at aaronwl dot com]

On Windows targets, weak symbols have not supported in GCC, and have never been
supported.  However, they have been supported in binutils for years, with
varying degrees of quality.  They are probably now reliable enough to be
supported by GCC.

As of 2004-10-25, weak symbols will break libstdc++-v3.  See
<http://gcc.gnu.org/ml/gcc-patches/2004-10/msg02723.html>.  I'm not sure what to
do about this yet.
