CAN_SEE error

I got bored and decided to make it so spells and skills can be settable by
moving the min_level assign to seperate files.  After doing so it appears
that the CAN_SEE macro no longer works.  I commented out the first error
in comm.c just to check and next time CAN_SEE is called it crashes.  I
have not made any chages to CAN_SEE or related macros in CAN_SEE.  Here's
the gdb output.

Program received signal SIGSEGV, Segmentation fault.
