Description

When building proton after doing cmake .. the make process is quite "noisy" generating a number of warnings that ought to be corrected.

One such warning is:
"Warning(451): Setting a const char * variable may leak memory."

This relates to the "const char *bytes;" in the pn_delivery_tag_t struct in engine.h

The swig documentation in http://www.swig.org/Doc1.3/Warnings.html suggests how to suppress this warning (due to the way the code works I believe that it's safe to suppress this case) by doing:

%warnfilter(451) pn_delivery_tag_t;

in the various python.i, perl.i etc.

I've make the changes locally and this indeed works.

I'll put together a review board request.
