Well, I've always disliked this (ab?)use of _POSIX_SOURCE, and in fact
the standard defines only a single way of using it, which is strictly
conforming applications defining it (or _POSIX_C_SOURCE these days) in
a compilation unit before inclusion of any header.

Isn't it sufficient, for the purposes of <soundcard.h>, to include
<machine/endian_machdep.h> and use _BYTE_ORDER?
