I believe the problem here is the "-std=c99" in William's CFLAGS.  The
meaning of "extern inline" in C99 is different from the historical GCC
meaning.  The C99 spec, section 6.7.4, says that "inline" gives you a
function that is completely inlined, with no external linkage possible, and
"extern inline" means that you inline calls to that function from within the
same compilation unit, but also leave behind an actual function that can be
called by external code.  GCC used to define "extern inline" to mean what
C99 now calls "inline", and "inline" to mean approximately what C99 now
calls "extern inline".

We need to put C99 detection into our configure script and adjust the inline
keywords accordingly.  In the meantime, William, remove the "-std=c99" from
your CFLAGS and let us know if that works.
