+/*  The traditional meaning of 'extern inline' for GCC is not
+  to emit the function body unless the address is explicitly
+  taken.  However this behaviour is changing to match the C99
+  standard, which uses 'extern inline' to indicate that the
+  function body *must* be emitted.  If we are using GCC, but do
+  not have the new behaviour, we need to use extern inline; if
+  we are using a new GCC with the C99-compatible behaviour, or
+  a non-GCC compiler (which we will have to hope is C99, since
+  there is no other way to achieve the effect of omitting the
+  function if it isn't referenced) we just use plain 'inline',
+  which c99 defines to mean more-or-less the same as the Gnu C
+  'extern inline'.  */
