  The default behavior of the glibc implementation of @code{getopt} allows
  mixing option and non-option arguments on the command line in any order.
  Other implementations, such as the one in Cygwin, enforce strict POSIX
  compliance: they require that the option arguments precede the non-option
  arguments.  This is something to watch out in your program's testsuite.

  Gnulib provides a module @code{getopt} that has support for ``long options''.
  Compared to POSIX, it adds a header file @code{<getopt.h>} and functions
  @code{getopt_long} and @code{getopt_long_only}.
