* newlib/libc/include/getopt.h (struct option): name field should be
	"const char *".
	* newlib/libc/stdlib/getopt.c (getopt_internal): Use fputs()/fputc()
	instead of fprintf() to save code space.  Fix signed/unsigned
	comparison.
	* newlib/libc/stdlib/getopt.c (getopt_internal): Add missing braces.
