Hi,
This fixing some of the pointer aliasing problems in
dlls/ole32.
(The compiler can assume that (void**)&ptr and ptr are
different entities, have nothing to do with each other
and move code around where it might break.)
Ciao, Marcus
Changelog:
Fixed some warnings from newer gccs in regards to
pointer aliasing problems by using unions instead of
using (void**)&ptr constructs.
