The pragma in it's alias form gives a warning, and is ignored. I think the
docs only mean to say the pragmas will compile. They don't say the
resulting code will work.

Have you looked at <http://developer.apple.com/technotes/tn2002/tn2064.html>?

GCC prefers __attribute__ over #pragmas in general. __attribute__((weak_import)) is the means for specifying a weak-linked symbol.

HTH,
