ecpg option --help alternative -? doesn't work in windows. In windows, the PG provided getopt_long function is used for reading the provided options.
The getopt_long function returns '?' for invalid characters also but it sets optopt option to 0 in case if the character itself is a '?'. But this works for Linux and others, whereas for windows, optopt is not 0. Because of this reason it is failing. I feel, from this commit 5b88b85c on wards, it is not working. I feel instead of fixing the getopt_long function to reset optopt parameter to zero whenever it is returning '?', I prefer fixing the ecpg in handling the version and help options seperate. Patch is attached. Any one prefers the getopt_long function fix, I can produce the patch for the same. Regards, Hari Babu Fujitsu Australia
