you have to make the setup-function available to the calling application
(pd).

declaring a function as "static" will make it _local_ to your file (and
inaccessible from other files, even if they are statically linked
together) according to the C language specs.

on super-secure operating systems (like w32) you will also have to
explicitly declare a function in a dll to be "exported" for use from the
calling app.
do this by using the EXTERN macro in m_pd.h

(using the macro is clever, since you won't have to deal with the
different OS; miller will do that for you)
