|
||||
* glibc's getopt(3) is useless: it is not POSIX compliant without jumping through
|
||||
non-portable hoops, and the method of resetting it is unclear (the man page
|
||||
on my system says set optind to 1, but other sources say 0). So, import
|
||||
OpenBSD's getopt_long.c into compat/ for use on Linux and use the clearly
|
||||
documented optreset = optind = 1 method. This fixes some strange issues
|
||||
with command parsing (getting the syntax would prevent any further commands
|
||||
being parsed).
