Hmmmm.

On some systems (PAs running hpux), you can't have a text/readonly data
item which is initialized to the address of another item.

ie

	.word foo

isn't valid if it's going into the text or readonly data section.

This is becaue the dynamic linker can't modify that memory location
at runtime if "foo" is resolved from a shared library.

Maybe you're running into a similar problem.
