Are you sure that you're building miscellaneous with llvm-gcc?  You can
verify this by running

mkoctfile -p CC

I have to *force* Fink's miscellaneous package to build with
llvm-gcc-4.2 on Lion because using the clang compiler (which is our
default) results in these errors.  It sounds like you're building with
clang, too.  What I use to work around this is to set the CC environment
variable before starting Octave, e.g.

$ export CC=llvm-gcc-4.2
$ octave
> pkg install -forge miscellaneous

Octave's build process by default encodes whatever compiler is being
used to build it into the mkoctfile build tool, and it sounds like
Homebrew uses clang to build Octave.
