getopt_long

[Scott Bambrough]

The attached program experiments with getopt_long.  It prints optarg for
each option, or (null) if optarg is NULL.  If I attempt to use the -o
option I get the following results.

$ ./getopt_test -o
optional argument: (null) 

$ ./getopt_test -o arg
optional argument: (null)
Non - option ARGV elements: arg 

This happens for me with glibc 2.1.2 on x86 and ARM.

The -o option is supposed to take an optional argument.  The
documentation leads me to believe that optarg will be set if an argument
for the option exists.  Have I missed something or is this a bug?
