A Gzipp'd file will start with a Gzip header and the uncompress function 
(probably) expects to be given a pointer the first byte of the 
compressed data, i.e. not a pointer to the header.

You probably just need to add an offset == to the size of the gzip 
header to the start of your data.

There's a full interface to zlib available in phobo\etc\c\zlib.d. so 
have a look through there.
