+ * These fix the following warning in GCC:
+ * warning: passing arg 1 of `ntohs' with different width due to
prototype
+ *
+ * Even if you declare an unsigned char or unsigned short variable and
pass
+ * it to htons or ntohs, this warning will be generated.  I believe
this is
+ * a gcc bug.  You can try to reproduce the bug like this:
+ *
+ * u_short foo(u_short bar) {
+ *   return htons(bar);
+ * }
+ *
+ * Using the reactos compiler settings this generates the error.
Unless I'm
+ * missing something, the active prototypes for htons and ntohs are:
+ *
+ * u_short PASCAL htons(u_short);
+ * u_short PASCAL ntohs(u_short);
+ *
+ * From winsock2.h.  Since the function above has exactly the same
signature
+ * as htons except for the required PASCAL (__stdcall) decoration, gcc
is
+ * erroneously detecting a narrowed value.
+ * </rant>
