If Wireshark is built without support for reading gzipped files with 
zlib (probably because you don't have zlib available), nothing.

If it's built with support for reading gzipped files with zlib, 
file_read is a macro that calls gzread, so it'll handle gzipped files; 
fread doesn't handle gzipped files.
