	Probe the compiler for the availability of the

	<util/delay.h> and <avr/builtins.h> appropriately.  Note that the
	modification is done by setting __HAS_DELAY_CYCLES on top of those
	files, which has been left overridable from the compiler
	environment (i.e., commandline -D option) on purpose.  Note also
	that _delay_us() and _delay_ms() can only use
	__builtin_avr_delay_cycles() if optimization is enabled as they'd
	otherwise try to pass a floating-point argument to it which is not
	allowed.  (The compiler does not seem to be able to convert it
	into an unsigned long internally, not even with a type cast.)
	However, not enabling optimization for them yields garbage timing
	anyway, due to moving the compile-time constant floating-point
	calculations from the compiler into the AVR.
	* configure.ac: Add detection of __builtin_avr_delay_cycles
	* include/util/delay.h.in: repocopied from delay.h
	* include/util/Makefile.am: added delay.h.in
	* include/avr/builtins.h.in: New file.
	* include/avr/Makefile.am: added builtins.h.in

2010-02-03  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

	bug #28756: Bug in AVR libc 1.6.7 (power.h for 8-bit AVR)
	* include/avr/power.h (clock_prescale_set): Implement as an inline
	function rather than a macro so it syntactically becomes a true
	function.
