Good catch!


BTW, another solution is to concatenate three messages into one.

if (stack->sym == last_sym)
         fprintf(stderr,
                 "%s:%d:error: recursive dependency detected!\n"
                 "For a resolution refer to
Documentation/kbuild/kconfig-language.txt\n"
                 "subsection \"Kconfig recursive dependency limitations\"\n",
                 prop->file->name, prop->lineno);


Personally, I prefer this.
It may be a matter of taste, though.
