POSIX also doesn't require getopt_long. But most GNU programs do, otherwise it's hard to implement support for --help and --version. And <unistd.h> does not declare getopt_long; only <getopt.h> does. To make all this clearer, I have essentially renamed 'getopt' to 'getopt-gnu' and added a new module 'getopt-posix'. Bruno
