Hi, i have now a build machine with gcc6 and try..

There is always some warning, i have push a first serie of patch https://code.wireshark.org/review/#/q/topic:gcc6

For dissectors, the last one is :
../../asn1/q932/packet-q932-exp.h:26:27: error: ‘q932_PresentedNumberUnscreened_vals’ defined but not used [-Werror=unused-const-variable]
../../asn1/q932/packet-q932-exp.h:18:27: error: ‘q932_PresentedNumberScreened_vals’ defined but not used [-Werror=unused-const-variable]
../../asn1/q932/packet-q932-exp.h:10:27: error: ‘q932_PresentedAddressUnscreened_vals’ defined but not used [-Werror=unused-const-variable]
../../asn1/q932/packet-q932-exp.h:2:27: error: ‘q932_PresentedAddressScreened_vals’ defined but not used [-Werror=unused-const-variable]

If there is a expert of ASN1 dissector generator ;-)

Cheers

I addressed the first warning of that sort with

        https://code.wireshark.org/review/13198

by moving the *definition* out of the header into a source file, leaving only a *declaration* in the header.  That way, you don't get unused tables in compilers that don't optimize it out and you don't get warnings from GCC.
