In short, yes, it does work for me.

I rolled back my patch (change *-mingw32* to *mingw32*) and applied
your patch to the libstdc++-v3 as found in GCC 3.2 and could
successfully build, install and smoke test:

1. Linux-hosted MinGW cross compiler (build=host=i686-pc-linux-gnu
   and target=mingw32).

2. Native MinGW compiler built on Linux (build=i686-pc-linux-gnu
   and host=target=mingw32) using the cross compiler produced
   by (1) above.

BTW, I built and installed only C and C++, and explicitly
specified "--target=mingw32" to configure.

I used GCC 3.2 and binutils 2.13 sources with MinGW patches
dated 20020817 and 20020903 respectively, as found at the
MinGW SF repository at http://sourceforge.net/projects/mingw/.

A minor thing to note was that the version of libstdc++-v3
configure.in that comes with GCC 3.2 had only two
"case "$target_alias"" statements - in any case, the second
"case" statement in your patch is a "sub case" in hpux of
a larger "case".

If this is good enough and no one else has had a problem
with this, I guess you can proceed with the check in.

Thank you once again for your help.

Sincerely Yours,
Ranjit.
