Hmmm ....a wild guess is that DJGPP makes the function inline and then 
unrulls the loop, (make five copies of gotoxy()) but does it make the 
executable 40Kb larger???
I assume that DJGPP's version of gotoxy() is a very complex function 
(????) but it should NOT be inline if it's so big!

Try this:
1 Disassemble your code (both version) and send them up to this 
newsgroup. 

2. Take a good look at the gotoxy() function, source is available on the 
net.

3. Strip the symbols, run strip (or whatever it's called),
i think you can do this from compilers command-line too.


BTW, the whole conio will not be linked to your exe-file.
