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).

Never trust an operating system you don't have sources for. ;-)
