Good idea.
Please use separate file for socket safe macros, look at how
safe_stdin.h made.
The name could be safe_sock.h, safe_net.h, etc.

bind() can return -1 if address is in use, e.g. it's in time_wait state.
Usually, you should wait (~30 sec or more, it depends on rtt) on it
until socket address will be available. If timeout exceeded, only then I
would exit with TBROK. Please check for errno 'EADDRINUSE'.
