This looks like a multilib issue -

man offsetof says #include <stddef.h>

I see there are a few stddef.h on my system, including:
     /usr/include/linux/stddef.h is just a blank line - who knows what
its there for. However
     /usr/src/linux-3.14.33/include/linux/stddef.h
and
     /usr/lib64/gcc/x86_64-slackware-linux/4.8.2/include/stddef.h
both have definitions of offsetof.

The fact that one of these is compiler-specific is what leads me to
suspect a multilib issue since one might expect a mulitlib system to
also have a /usr/lib/gcc/x86_64-slackware-linux/4.8.2/include/stddef.h
but I don't have that on my multilib system. My guess is that you're
trying to build a 32bit version and so the compiler can't find its
stddef.h (its not there). You can compile a 64bit version on multilib
i.e. don't do the /etc/profile.d/32dev.sh thing) and it should compile OK.

 I am not sure what you are using pulseaudio for Gilles, but you could try
apulse, which will detect multilib automatically.
