Make strcmp in main.c#_start_logging explicit
Currently the don't pipe to standard output options are in the else branch, because of usage of strcmp such as if ( strcmp(a, b) ) { .
This gist https://gist.github.com/miksago/cfb3f41784bff197facc includes changes to make the comparison of strings explicit as well as changes the logic to be:
if config->access_log == '-'; then
handle standard output
else
handle logging
