Andreas Rheinhardt	4393331250	avcodec/dirac_dwt: Avoid conversions between function pointers and void* Pointers to void can be converted to any pointer to incomplete or object type and back; but they are nevertheless not completely generic pointers: There is no provision in the C standard that guarantees their convertibility with function pointers. C90 lacks a generic function pointer, C99 made every function pointer a generic function pointer and still disallows the convertibility with void *. Both GCC as well as Clang warn about this when using -pedantic. Therefore use unions to avoid these conversions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
