This will introduce a warning:
    computername.c: In function ‘dns_gethostbyname’:
    computername.c:90:9: warning: suggest parentheses around
assignment used as truth value [-Wparentheses]

I happen to think
+        if (!(newbuf = HeapReAlloc( GetProcessHeap(), 0, extrabuf, ebufsize )))
+            break;
+        extrabuf = newbuf;
would be slightly nicer anyway.
