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?
