[pulseaudio-discuss] [PATCH v3] netbsd: Stop depending upon nonstandard __WORDSIZE

There is no way to check CPU type in a portable way across ABIs.

Go for pa_mult_s16_volume() version without need for int64_t.
It's actually the same as in src/tests/mult-s16-test.c.

This change fixes build on NetBSD.
