When building the stable or head zaptel with kernel  linux-2.6.11-1.35_FC3.  The
module compiles but it never used to give this message on FC2.

Anyone got any ideas?

Who said it's an error, Linus just does not like it and thinks says it's
incorrect, it causes no errors, and when you have multiple kernel sources on the
same machine it makes life much easier.

I would agree that going through multiple symlinks is bad practice, this could
also be Linus' argument, or maybe it's multiple times through the same
symlink in the case of a kernel compile.
