SirenACM is the siren audio codec using the ACM.dll interface as used within MSN Live. It misses some exported functions from msvcr80.dll which appear to be dumb re-implementations or references to existing functions from kernel32

Below a patch to add these functions:

beware that msvcrt8 works in a different way it uses side by side manifests
I'm not sure that the current loader can work using it in a "blind way"
perhaps on win9x it's enough to put 3 dll in system dir.

imports from msvcrt80 are:

we can only hope that the coded does not want to call an exception :)
but by looking at imports it does not look like cpp code
