first off: please _always_ reply to the pd-list and not just me; the
list is not just a way to get into contact with others, but also a way
to learn things "passively" (e.g. by lurking on the list or by reading
the archives)...

ok, unfortunately your make excerpt didn't tell me enough, since you
should have done a "make clean" before. (only the linking stage is
executed since the compilation of additive~.o is already up-to-date).

miller's pd is compiled with M$VC-6 (i think), you have to tell gcc that
 you are linking against such library.

try to use the "-mms-bitfields" cflag to gcc when _compiling_ your external.
and tell us what happens.
