Stronglight ought to go lower than 38T. And, Bob Hovey wrote:

I distinctly remember putting a 36 on my 93.

Just a couple of observations: Not only does Sheldon Brown declare 38 as the minimum, but so does Sutherland IV. That takes care of authority, w/o even checking Cyclo-Pedia.
So, I got out a Stronglight 93 arm and an available 36 tooth (Campy, from the ugly triple) to eyeball the things. If someone were willing to do almost anything to get a 36 to run on a Stronglight, it would be possible. Of course, you would have to grind off the tops of the arms, down to just about the top of the chainring bolt hole (<1 mm clearance). Then find a ring that would sit on the arms - oddly enough, the Campy 36 is pretty close, maybe half a mm too big in radius.
For all that, the Stronglight 99 and its clones (86 mm BCD) do turn up occasionally, and have much greater flexibility.
Good luck!
