[SR-Users] [sr-dev] Branch 5.0 created

[Daniel-Constantin Mierla]

They were reported in the past, iirc, but apparently only by a specific
version of compiler, or maybe some specific flags to gcc.

On kamailio.org, which is a 32b jessie, the results of 'make' are clean:

...

CC (gcc) [kamailio]        core/rand/isaac/rand.o
CC (gcc) [kamailio]        core/cfg/cfg_select.o
CC (gcc) [kamailio]        core/cfg/cfg_ctx.o
CC (gcc) [kamailio]        core/cfg/cfg_struct.o
CC (gcc) [kamailio]        core/cfg/cfg_script.o
CC (gcc) [kamailio]        core/cfg/cfg.o
bison -d -b core/cfg core/cfg.y
flex -o core/lex.yy.c core/cfg.lex
CC (gcc) [kamailio]        core/lex.yy.o
CC (gcc) [kamailio]        core/cfg.tab.o
LD (gcc) [kamailio]        kamailio

No warning printed.

Are you running special gcc or with other flags than the default?
