No, it does not and will not.  While the two technologies share the same
underlying compression codec, they each use the codec quite differently.
 A ZIP file is an archive of one or more files and directories each
individually compressed, or possibly not compressed at all.  A GZIP file
is a compressed version of a single file's contents.  Those contents
could be, and often are, that of a TAR file which itself contains one or
more uncompressed files and directories; however, this method of
archival is completely different than that of a ZIP file.

If you want to extract an actual GZIP file, take a look at
Zlib::GzipReader included with the standard library:
