Compile a file to byte-code for faster loading.
byte_compile_file (String_Type file, Integer_Type method)
The byte_compile_file function byte-compiles file
producing a new file with the same name except a 'c' is added
to the output file name. For example, file is
"site.sl", then the function produces a new file named
site.slc.
The method parameter is not used in the current
implementation. Its use is reserved for the future. For now, set
it to 0.
