Ahah! That certainly seems to work, adding:
#if defined(__GNUC__) && ((__GNUC__ > 3) || ((__GNUC__ == 3) &&
(__GNUC_MINOR__ > 3)))
//
// The following code emits warnings when built with -pedantic, and there
appears
// to be no other way of suppressing these warnings as use of __extension__
has no
// effect, so declare the rest of this header a system header.
//
# pragma GCC system_header
#endif
near the end of the header, suppresses those warnings.
Any downsides or objections to this?
Thanks, John.
