re PR target/61407 (Build errors on latest OS X 10.10 Yosemite with Xcode 6 on GCC 4.8.3) 

PR target/61407

	* config/darwin-c.c (version_as_macro): Added extra 0 for OS X 10.10
	and above.
	* config/darwin-driver.c (darwin_find_version_from_kernel): Removed
	kernel version check to avoid incrementing it after every major OS X
	release.
	(darwin_default_min_version): Avoid static memory buffer.

	* gcc.dg/darwin-minversion-1.c: Fixed formatting
	* gcc.dg/darwin-minversion-2.c: Fixed formatting
	* gcc.dg/darwin-minversion-3.c: Fixed formatting
	* gcc.dg/darwin-minversion-4.c: Added test for OS X 10.10
