the setup tree contains its own copies of the zlib and bzlib trees; 
thue, they are compiled under the same runtime that setup is.  If setup 
is a 'mingw' app, then so are the internal, statically linked libz and 
bz2lib.

I imagine that the reason Igor used popen and zcat is simply that it was 
easier than directly interfacing to the library.  Perhaps that issue 
could be addressed in a later patch (along the lines of the compress_gz 
class, which also provides uncompression capabilities?)
