  There are two possible means to this end when compiling with GCC,
  one when compiling with a standard C99 compiler, and for other
  compilers we're just stuck.  At the moment, this issue only
  affects the Cygwin target, so we'll most likely be using GCC.
 
  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'.  */
