But in your implementation of this you've already pre-defined a macro
(streq) - why not predefine a macro or inline function called, say,
is_member, to do the work and then your macros for each indivdual case
can be trivial as well as more readable.

I see.  But the point is moot if strchrnul is not implemented on the
system.  In addition I think the intent is slightly less clear, but
maybe that's just me.
