Comment (by yurivict271):

 Morover, when I add {{{-std=c99}}}, compilation breaks:
 {{{
 src/common/di_ops.c:158:5: warning: implicit declaration of function
 'typeof' is invalid in C99 [-Wimplicit-function-declaration]
     tor_free(victim);
     ^
 ./src/common/util.h:90:5: note: expanded from macro 'tor_free'
     typeof(&(p)) tor_free__tmpvar = &(p);                      \
     ^

     ^

                  ^

                  ^
 }}}

 So it is something else, not {{{c99}}}.
