libdes's md5 is starting to show its age. It's abusing unsigned char *
for void * which causes llvm22 to error with
md5.c:400:14: error: incompatible pointer types passing 'unsigned char (*)[65]'
to parameter of type 'POINTER' (aka 'unsigned char *')
[-Wincompatible-pointer-types]
The crude patch below replaces the hand-rolled memcpy() and memset()
with the libc ones. (Redefining POINTER to void * causes other problems).
