In /src/backend/utils/error/elog.c and /src/backend/utils/error/exc.c
you have t change

	extern int	sys_nerr;

	to

	#ifdef __CYGWIN__
	#  define sys_nerr _sys_nerr
	#else
	   extern int sys_nerr;
	#endif

PostgreSQL contains a empty version of tcp.h in the /src/win32 directory
together with a readme file of what to do with it,
