since we are duplicating something that comes from something else that
has been duplicated out of windows WDK here it might be a reasonable
safety check to verify that our duplicated values match our
expectations?
#ifndef MEM_COALESCE_PLACEHOLDERS
#define MEM_COALESCE_PLACEHOLDERS 0x00000001
#else
static_assert(MEM_COALESCE_PLACEHOLDERS == 0x00000001, "...")
#endif
either way, this is straight forward.
