Will cause this warning.
sa.sin_port = (__extension__ ({ register unsigned short int __v, __x =
(siteinfo->port); if (__builtin_constant_p (__x)) __v = ((((__x) >> 8) & 0xff)
| (((__x) & 0xff) << 8)); else __asm__ ("rorw $8, %w0" : "=r" (__v) : "0" (__x)
: "cc"); __v; }));
__v = ((((__x) >> 8) & 0xff) | (((__x) & 0xff) << 8));
is the part which is causing the warning. The issue is the (__x) >> 8 is
implictly casted into int.
