Looks like socklen_t is signed in your environment, which results
in a warning. Try the following patch:

--- a/src/core/ngx_inet.c
+++ b/src/core/ngx_inet.c
@@ -233,7 +233,7 @@ ngx_sock_ntop(struct sockaddr *sa,

/* on Linux sockaddr might not include sun_path at all */

- if (socklen <= offsetof(struct sockaddr_un, sun_path)) {
+ if (socklen <= (socklen_t) offsetof(struct sockaddr_un, sun_path)) {
p = ngx_snprintf(text, len, "unix:%Z");

} else {

Alternatively, you may just ignore the warning, it's harmless.
