Is this the only line in your program?  If so, then the program compiled under
DJGPP will always run slower.  This is because DJGPP spends a lot of time in
startup code compared to a single library function like printf().

Also, the line you provided is incomplete.  printf("%.6f") is a meaningless
call.  You will need to post the code that is giving you problems.

Look at sprintf().  It does everything printf() does, except the output is sent
to a character array (string) which is automatically null-terminated.
