George Koehler 50a7031007 Don't use '-' in option string to getopt(). ... @dram reported a build failure in FreeBSD at https://github.com/davidgiven/ack/issues/1#issuecomment-273668299 Linux manual for getopt(3) says: > If the first character of optstring is '-', then each nonoption > argv-element is handled as if it were the argument of an option with > character code 1.... > > The use of '+' and '-' in optstring is a GNU extension. GNU/Linux and OpenBSD handle '-' in this special way, but FreeBSD seems not to. If '-' is not special, then em_ego can't find its input file, so the build must fail. This commit stops using '-' in both em_b and em_ego, but doesn't change mcg. Also fix em_ego -O3 to not act like -O4.		2017-10-29 23:25:07 -04:00
