No. The "s:" in optstring and 1 as a second value in {"start",1,0,'s'} always
makes next token a parameter.

Try to compile and run following example:

#include <stdio.h>
#include <getopt.h>
struct option opt[] = {
int main(int argc,char **argv) {
	int idx,c;
		printf("option: %c, optarg: %s\n",c,optarg);

It gives:
arturcz at szczaw:/tmp/g$ ./gol --letter-a -2d
option: a, optarg: -2d
arturcz at szczaw:/tmp/g$ ./gol -a -2d
option: a, optarg: -2d

Wish I know how to do it. Simple grep in sources gives no results.
That's why it is so mysterious to me and I am asking for help at wider

Because only apache/php4(module) is a problematic combination I suspect
an apache. If it is sufficient for you I have no objections against
reassigning this bug to apache package.
