Stripping D symbols?

[Heywood Floyd]

..ok, I got bored and installed Ubuntu I tried it, and there it worked fine!

# strip sym
# nm sym | grep Bunny
nm: sym: no symbols
# _


Great! The program runs fine too.
(And the binary went from a size of 399Kb to 191Kb! Woah! That's more than half gone!)

Hm, but how to I go about his now? Seems the OSX-strip is acting funny? Or could it have something to do with DMD still? Maybe I should ask in some darwin-forum about strip...
