>It is likely that the output of mib2c will be further customized

by editing the mib2c.conf file to add or remove whatever you need
with the resulting C sources.</P
><P
>The UCD autoconf-style configuration does not apply to eCos.
So if you add a completely new MIB to the agent, and support it
using mib2c so that the my_new_mib.c file contains
a init_my_new_mib() routine to register
the MIB handler, you will also need to edit a couple of control
files; these claim to be auto-generated, but in the eCos release,
they’re not, don’t worry.</P
