Hello,

I’m trying to build nginx 1.5.3 on Cygwin using Windows 7. I see the  
following output during “make”:

I would appreciate any help to fix this. Thank you!

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.

Sure, committed. Thanks for testing.

Hi Maxim,

Thanks so much. Your patch worked great.

The build was failing without that change.

Is there any way that patch can be incorporated into the main source, so  
that it doesn’t happen again in 1.5.4?

Thanks again, I really appreciate it.

## Best regards, Kevin
