Hehe. :) Until then, I guess it's time to use the context pointer of CFArrayApplyFunction to pass structs of the downward funargs. 2 down, 27 more to go.

Well, maybe when Apple posts the sources for their gcc-4.0.1, we'll find some juicy gossip in it. Maybe not ... now that I've mentioned the possibility :)

I also discovered that this is (mis)documented in the standalone pdf release notes, but not documented within the release notes installed by Xcode 2.2. Per the standalone release notes:

"Nested Function support: We are deprecating nested functions (a gcc extension to C) in this release. For now, nested functions will cause a warning."

Unfortunately, it's not a warning, it's an error.

Removing gnu extensions from a gnu compiler, due to an Apple stack mangling bug with CFM, seems quite odd to me.

I wonder if it has something to do with the discovery alluded to in this thread:

Apparently nested functions in a MachO app combined with a CFM plugin brought in to the process would cause major mayhem.

The new xcode 2.2's gcc 4.0.1 compiler update has apparently dropped support for nested functions. Apple's release notes for gcc do not even mention this change... :(

Before I downgrade to gcc 4.0, is there a command line option to re-enable nested functions?

Why were they disabled? Are they going to be re-enabled?
