Rebased on master (a24979a2d7) and ignoring anything PJSIP-related, 
still getting a bunch of warnings with gcc (Ubuntu 11.2.0-7ubuntu2) 
11.2.0 (attached).

Compiler flags used:

-Wformat
-Werror=format-security
-Wdate-time
-Wall
-Wstrict-prototypes
-Wmissing-prototypes
-Wmissing-declarations
-Wl,--warn-common

As for the recent fixes, I guess we just need to wait for 16.27.
