Uhh .. Thaddy, I'm using 3.0.4 and the warning is still there (at least in Linux). Does it not depend rather on the version of ld (the linker)?
There's a very slight chance it is just in 3.2.0 but I really think the linker behavior has changed since 3.0.4. provided you have an up-to-date linker. 2.21 won't do.
More in detail: FPC changed the way it talks to the linker and the warning is harmless.
