Most probably not. However, could you run with --debug-building and send me the log off-list, so that I can take a look.

Well, you can bring this up with Windows developers -- and ignore that
is say "specified".

The command is the result of running:

        powerpc-linux-g++.exe -print-prog-name=ar

It's generally not so good idea to be in commnad line shell of the Windows 
operating systems, and then run commands for the GNU/Kernel32.dll 
operating system, because while this appears to work, you'll run in a
 number of issues like this one.

So, you should either:
- Build from cygwin shell,
- Explicitly specify ar binary, as follows:

        using gcc : 4.1.1 : powerpc-linux-g++.exe : <archiver>C:/Cygwin/..../ar.exe ;
