There are only a few places where -Khost and -Kno_host makes a
difference. Obviously, it affects the value of the preprocessing
predefine __STDC_HOSTED__, but otherwise, the only effects I see
on a quick grepping are:- whether "inline" on "main" is ignored- whether the known library function rewrites/side
effectchecks are enabled. Other than what you'll find in /usr/ccs/lib/intrinsics, the only other rewrites are:-
strcpy(X,"string") -> BMOVE of "string" if X has no side effects- strncpy(X, "string", sizeof("string")+1) -> as above-
strlen("string")-> the length- some "redundant loop" unrolling, presumably since we don't know about potential side
effects
But, like with all optimizations, your mileage will vary. You can
try it with and without and see how much of a difference it makes.

I can see doing either, but that's the team's decision.
The fix won't be out until Update Pack 3 at least (which is 3 months away).
It **MIGHT** make an update pack but I don't know.
