6.7.4, says that &quot;inline&quot; gives you a function that is completely inlined, with no external linkage possible, and &quot;extern inline&quot; 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.&nbsp; GCC used to define &quot;extern inline&quot; to mean what C99 now calls &quot;inline&quot;, and &quot;inline&quot; to mean approximately what C99 now calls &quot;extern inline&quot;.
<br><br>We need to put C99 detection into our configure script and adjust the inline keywords accordingly.&nbsp; In the meantime, William, remove the &quot;-std=c99&quot; from your CFLAGS and let us know if that works.<br>-- <br>
