In my quest of making gzip work for my application on windows, I found
the following bug :

int main(int argc, char *argv[])
{
 std::ofstream strm("test.gz");

 boost::iostreams::filtering_ostream  sink;

 /* Push gzip compressor */
 sink.push(boost::iostreams::gzip_compressor());

 /* Push file writer */
 sink.push(strm);

 #if 0
 /* This does not work */
 sink <<"  OBJ   N"<< std::endl;
 #else
 /* This works */
 sink <<"  OBJ N"<< std::endl;
 #endif
}

The first string results in a invalid gzip file i.e invalid compressed
data--length error. I am aware this might be a bug in zib lib. It
works on without any problems on linux.

Does anyone use gzip on windows on a regular basis ?
