Has anyone been able to build a .so for anything with a static function
call?  I get
t.s:21: Error: "instruction/operands mismatch" -- Statement 'jbsr ___main,a1' ignored

(This is 68k.)  This is with new gcc/new gas.

New gas won't build unless you replace "(unsigned) -1" with
"(unsigned short) -1".
