I'm having trouble compiling 2.6.27-rc1 for ARM OMAP.

I'm using gcc 3.4.4 (specifically, one used for
cross-compiling for ARM)

The file that fails to compile is kernel/time/tick-common.c

Here is the compiler message:

This seems to be related to commit 0bc3cc03fa6e in Linus' 2.6 tree.

Any assistance you can provide would be appreciated.
