You can move the block 

#ifdef __NetBSD__
#include <soundcard.h>
#include <sys/soundcard.h>

around line 18 of OssAudioRenderer.cpp behind the block of standard includes,
including the inclusion of unistd.h.

The problem seems to be, that soundcard.h defines _POSIX_SOURCE, includes
<machine/endian.h> which includes, via <sys/endian.h> -> 
<machine/endian_machdep.h> -> <machine/byte_swap.h> -> <sys/types.h> which
in turn only defines u_long and u_int only if _POSIX_SOURCE is _not_ defined,
before _POSIX_SOURCE gets undefined again in soundcard.h.

So, <sys/types.h> gets included in a _POSIX_SOURCE context, but the rest
of the includes does not impose these restrictions.

I think, <unistd.h> should use 'unsigned long' instead of u_long and
'unsigned int' instead of u_int in the prototype for profil(), but this
is more a question for our standards experts.
