Easiest way to get file size (unix)?

The compiler is not the issue - the question is does the OS rtl's have
a function that will do the job. The answer is yes - see later.

Do a "man stat" for a function that returns detailed information on
files. This is, I believe, also available in Microsoft C and Borland
C, so is potentially much more portable than "filelength()".
