Actually, three ways:

Ada.Stream_IO.Size, given an open (Stream_IO) file.

The latter is what I'd do for the problem at hand, although the other 
packages are probably easier to understand. (OTOH, Stream_IO is closest to 
the underlying I/O APIs on every target I've worked with, so it may be more 
familar.)
