The "undefined reference" errors result from the order of libraries,
which in turn is determined by the order library names in the
associated *_LIBS makefile variable.

Specifically, '-lasyn' and '-lautosave' must appear _before_
the other four Base libraries.

eg.


MYIOC_LIBS += asyn
MYIOC_LIBS += autosave
MYIOC_LIBS += $(EPICS_BASE_IOC_LIBS)


For details about why this is necessary, search for
"single pass linker".
