	1672 lines is correct. Let's see. x86.S uses a symbol named
_LASTBANK which is defined in the included file "mapper.h" as
LASTBANK. LASTBANK is declared in dynrec.c. I guess the assembler on Linux
is a little more forgiving than on OpenBSD when it comes to defining
globals. Look in mapper.h and after the following line:

#define _LASTBANK LASTBANK      /* Last memory page code executed in */

Add the line:

extern unsigned int LASTBANK;

And see it that fixes the problem. If it does, I'd wager that another
global will experience the same difficulty. Let us know how it turns out.
