(late comment due to vacation -- wish it could have been even later ...)

by bending a should, long options can be supported by getopt(3)
just add the single option flag '-' that takes a mandatory value
and use the --name=value form for long options with values

not the way I do it, but also not prohibited by posix

also, the ksh-integration provides getopts(1) and the underlying ast::optget(3)
that provides getopts(1) and getopt(3) compatibility and extensions for long
options, a mechanism for long options with or without a corresponding option flag, 
l10n long option translation, and pre-defined { --help --man --html } options

shell scripts using getopts(1) and utilities using optget(3) use the same interface
