Thanks - fixed now. My gcc (3.4.6-r1 from Gentoo did not warn)

Thesecond time modpost runs vmlinux is used to pick up symbol
information to check that all symbols are valid etc.
The alternative was to trust the symbols being read from Module.symvers
and that would be OK in most cases but I could imagine situations where
Module.symvers was deleted but vmlinux kept.
So therefore the more expensive solution to run modpost twice on vmlinux
was chosen.
