Wouldn't be the register_all_protocols() function problematic?
We could create a plugin directory with all its paraphernalia and have
the asn1 dissectors be loaded like a plugin.
But still the best thing would be to have the asn1 generated
dissectors inepan/dissectors and have them built from the Makefile.
For the warnings we could have asn2wrs.py prepend the #pragma for
unused static function right bellow the signature to the generated
code (that's an ugly fix but I do not find a feasible way to have
asn2wrs not creating the unused functions).
The rest is monkey business: just to add the generated targets to the
Makefile[s] like this:
packet-h248.c: ../../asn1/h248/packet-h248-template.c \
../../asn1/h248/packet-h248-template.h \
../../asn1/h248/h248.cnf \
../../asn1/h248/h248v3.asn
[TAB](cd ../../asn1/h248 && make copy_files )
packet-h248.h: packet-h248.c
