Ok, the file where the compilation error occurs did not include
stddef.h, so I added the include, and now pulseaudio compiles. I
guess stddef.h gets included by another header with the default
toolchain, and not with the multilib toolchain.

The other errors were due to antique headers installed in /usr/local.

Thanks for the help.
Regards.
