Since oldtimer is an absolute address, you need:

lcall *_oldtimer

However, IIRC this will not compile with binutils 2.8.1. If you need the
code to be compatible with binutils 2.9.5.1 beta and 2.8.1, then omit the
asterisk (*). This syntax correction between 2.8.1 and 2.9.5.1 beta is a
PITA.

Bye,
