two points:
1/ a handle can have any value... it's up to the DLL to decide what
   value it really is (pointer, index into an internal array, key
   to look up in a set...). in msacm case, since 16bit handles are
   not implemented yet, you cannot really tell
2/ you can leave the semi-stub as it is, mainly when the handle is
   NULL (which is in lots of cases for acmMetrics). However, since
   no 16 bit handle can be created, acmMetrics16 will only be called
   with NULL handles, since the semi-stub

so, I'd propose to let acmMetrics16 call acmMetrics only if hao is 0
