There is no way to check CPU type in a portable way across ABIs.
Checking for sizeof(void*) is reasonable since most platforms will
report correct values. One exception is x32, but since it's halfbaked
never finished and almost not needed any more - we can ignore it.
The check is needed only to print a debug message, no functional
change.
There is also a reference to __WORDSIZE in src/pulsecore/sample-util.h.
This change fixes build on NetBSD.
What error are you getting, and how come it does not affect
src/pulsecore/sample-util.h as well?
