Many of the warnings were newly visible after the DBPRINT macro was modified, but the pedantic warnings also caught existing printf family usage which was not strictly correct. Mostly replacing 0x%x with %p for pointers, adding (void *) for those and other pointers, %td for ptrdiff_t, but also changing some function parameters from UNSIGNED (uintptr_t) to int where that was the more appropriate type.
