There is a missing function.  The only real fix is to write
an implementation for the function. Sometimes you can
workaround by using more builtin libraries (when the missing
function is invoked by a 'native' (ms) library - something
that obviously never happens with builtin (wine) libraries)

Also, this is often not a real problem : if the Api is not
called, the app can work correctly. If it's called, it's a
crash of course.
