We can't tell unless you post some code fragment.

If your strings are constant (i.e., you don't need to format them with 
"%d", "%f" and such likes), use cputs, which is faster.  If you have a 
buffer with video attributes ready, or if you don't care about the 
attributes, use `dosmemput' to blit it directly to the VRAM.

None.  `cprintf' was already compiled (with -O3) when the library was 
created.  Nothing you do during compilation of your program can change 
the code inside `cprintf'.
