Yeah, it looks like the double dash long options got added without
ever being documented.

For the record, they were added here:

Sat Mar  6 15:08:59 1993  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

	* gcc.c: Handle long options by translation to old-style ones.
	(translate_options): New function.
	(option_map): New table.

and the table has been kept more or less up to date ever since.
