If you have...
void myfunc(char buf[16]) {
printf("%d\n", (int) sizeof (buf));
}
...this will print sizeof (char *) instead of 16, so this fixes a piece of
code that assumed the latter instead of the former.
This was a _ton_ of changes, made 15 years ago, so there are probably some
problems to work out still.
Among others: Engine/Base/Stream.* was mostly abandoned and will need to be
re-ported.
Still, this is a pretty good start, and probably holds a world record for
lines of changes or something. :)
