It looks like you are having problems because of local
redefinitions of valgrind requests.
The usual way to do is to just include valgrind.h or memcheck.h or ...
and then use the requests defined in these files.
E.g.
...
char magic_foople_zone[0x1000];
...
(void) VALGRIND_MAKE_MEM_NOACCESS(magic_foople_zone, 0x1000)
A.o., the valgrind regression test testing such requests
have no special thing to do to compile cleanly in 32 bits or 64 bits.
Using the include files provided in valgrind will also work in the
(unlikely) case the 'magic' instructions of a client request would
change in a newer valgrind version.
