I'm not sure why you are seeing this error but I'm not, but I committed a cast that should fix it.

David Smith, Thanks for your fix "Compile fix for runtime/vma.c" Now things are looking fine.

The kernel has lots of these errors, but disables the warning explicitly:
# disable pointer signed / unsigned warnings in gcc 4.0 KBUILD_CFLAGS += $(call cc-disable-warning, pointer-sign)
