I forget, does the VAX have a "load address" instruction?  Lack of this
instruction is the most painful thing about doing PIC on a PDP-11, and since
it's not at all unusual to handle pointers to functions or to global data
structures in C, this will bite you a lot (since you need to do math with
the PC every time you build a pointer, which could normally be loaded an
immediate value of the absolute address).  Pointers to data structures on
the stack would have to be computed anyway so that shouldn't be a problem...
