It is strange. file_gets() is typically #define as gzgets() when
compiled with zlib. The return of gzgets() is the same as fgets()
(which is used when zlib isn't present) - a char *. I noticed that
you're using an unsigned char (guchar), but a test program I made
outside of Wireshark works fine with that too. Want to send a patch of
your changes so we can try it also?
