Except these source files are assembly code. ;-) The source would need to take care to place each function into a subsection of its own. These are somewhat interweaved actually, e.g. itoa_fast and itoa_fast_width (IIRC) would share the same source code (they are just different entries into the same code). But yes, the standard (slow) itoa functions would be in a different object module, thus normally not linked (and subsequently, if no other division was used inside the program, the division subroutine would be avoided as well). -- cheers, J"org .-.-. --... ...-- -.. .
