The following patch is necessary to restore Solaris Go bootstrap after
your patch went in, to fix

/vol/gcc/src/hg/trunk/local/libgo/go/os/stat.go:22:29: error: argument 1 has incompatible type (cannot use type syscall.Timestruc as type syscall.Timespec)
/vol/gcc/src/hg/trunk/local/libgo/go/os/stat.go:55:60: error: argument 1 has incompatible type (cannot use type syscall.Timestruc as type syscall.Timespec)

	Rainer

	* go/os/stat_solaris.go: New file.
	* Makefile.am (go_os_stat_file): New variable.
	(go_os_files): Use it.
	* Makefile.in: Regenerate.
