Just a guess, but is it possible that the file is opened in DOS 'text' 
mode?  DJGPP defaults to this mode, which converts CR/LF into LF on input 
and LF to CR/LF on output.  If the raw numbers happen to be expressed 
with one of these codes (a CR/LF 0x0d 0x0a) in the file, then the io 
routines would convert this to one character (LF 0x0a) and would make the 
file seem shorter than normal.  On the other hand, if it converts writing 
out, it should convert coming in, and the net effect would be NIL 
(correct?).  Maybe the file is opened in binary mode, but read back in 
text mode?  Don't think this is too likely though.
