Fixed deprecated features, now compiles with DMD2.058 Also changed Array allocation policy: Now doesn't reallocate but malloc's, followed by a memcpy (no free). (this fixes a crash while compiling druntime. Same bug in dmd)

module dmd.DYNCAST;

enum DYNCAST
{
    DYNCAST_OBJECT,
    DYNCAST_EXPRESSION,
    DYNCAST_DSYMBOL,
    DYNCAST_TYPE,
    DYNCAST_IDENTIFIER,
    DYNCAST_TUPLE,
}
