I was just hit by this today

src/cmdline.c: In function ‘update_arg’:
src/cmdline.c:453:9: warning: variable ‘stop_char’ set but not used [-Wunused-but-set-variable]
   char *stop_char = 0;

is there anything I can do to help move this bug along to get it fixed?

I propose attached patch to fix this compilation warnings.

I've fixed these three warnings but probably more warnings could be produced with other kind of parameters.
