Why did you remove the workaround in tar_input.rb?  I don't see how  
the second half of your patch would affect it.

I seem to recall the hack in tar_input.rb exists for MSVC6.  I don't  
recall any known way to reproduce it.  Something in the gzip header  
would cause inflate to fail incorrectly.

Since gzip is just an extra 10 byte header added to the front of the  
inflate algorithm, there should be no reason to remove the hack.
