* [Bug libc/4690] New: getopt_long "--arg=val" and "--arg val" are not the same for "optional_argument"

When doing long opt processing, --arg=val and --arg val are interchangeable for
either no_argument or required_argument. However when using optional_argument,
optarg is set only if the form --arg=val is used. If the form --arg val is used
then the val is reported as an unknown argv option.
Granted that it may be a vague choice in determining that val is intended for
--arg vs. a value of it's own and therefore best left to the single form of
--arg=val, but all documentation related to getopt() and family refers to the
two forms being interchangeable.
I would like to request future releases of glibc document this in their online
manuals and man pages.
Thank you :)

Can you cite where you saw the two forms are interchangeable?
E.g. man getopt:
A long option normally begins with `--' followed by the long option name. If
the option has a required
argument, it may be written directly after the long option name, separated by
`=', or as the next argument
(ie. separated by whitespace on the command line). If the option has an
optional argument, it must be
written directly after the long option name, separated by `=', if present (if
you add the `=' but nothing
behind it, it is interpreted as if no argument was present; this is a slight
bug, see the BUGS).
