Do not use __ptr_t.
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired. Tested for x86_64, and with build-many-glibcs.py. * malloc/mcheck.c (old_free_hook): Use void * instead of __ptr_t. (old_malloc_hook): Likewise. (old_memalign_hook): Likewise.
