The Windows targets use GNU binutils as and ld.

However, version scripts only seem to be supported for ELF targets; 
Windows uses the PE variant of COFF.

The equivalent mechanism on Windows is the 'DEF' file, which 
unfortunately is not as expressive as version scripts, but it does have 
a few features version scripts don't, such as by-ordinal linking. 
Unfortunately DEF files do not support wild-card patterns either.

Actually, at present, this is not so much worse than on Linux ELF, which 
exports 65662 dynamic symbols from libgcj.so.10.0.0.

I will figure out what is necessary to generate a DEF file properly 
sometime soon, but in the meantime I think this can go in.
