You need to add baseClasses.c to GEN_SRCS in kaffe/kaffeh/Makefile.am, and to
re-autogen everything. Continue until it works without linkage errors ;)

It may be a better long run solution to split the bits needed by both kaffevm
and kaffeh into a separate library, than to copy the same code into kaffeh and
kaffevm. that seems to be somewhat redundant ;)

cheers,
