Probably because these functions are actually unused by any clients,
and the lazy linker used on Linux doesn't care, wheras Solaris linker
is more strict.  You could probably make the Linux linker more strict
with the right arguments.

Since core-scache.h includes memchunk.h anyway, it will always be
available to anything that previously included core-scache.h.  As I
said PulseAudio builds okay with this change, no issues with other
things not finding it.

As I said in my comments, I do not really care how the headers are
organized.  If creating a new separate header file with only the
#define that can be included from core-scache.h and pstream.c, that
would obviously also be fine.  There are probably a million ways to
fix this sort of issue.  If you instruct me how you would prefer this
to be organized, I can create a new patch.

Sure.  Do you need me to split this file into two patches for you?
