"Dynamic" selector issues

Hello there,

I witnessed something strange in the objc runtime :

  - When I create a SEL from a selector name like `selector = 
sel_getUid("foo")
  - It returns NULL when there is method declared as "foo" in my program
  - Or returns a real selector if a class responds to "foo" in my code
  - Whereas when I do @selector(foo), I do get a proper selector.

I tested this on a Linux box with gnustep-base-1.8.0. On OSX, this 
works just fine. So is there something to do with an obscure gcc 
option, or is this related to differences in objc runtime ?

TIA,

  -- Sébastien
