/* System dependencies in the W3 library * $LynxId: www_tcp.h,v 1.53 2011/05/24 23:48:50 tom Exp $ * SYSTEM DEPENDENCIES System-system differences for TCP include files and macros. This file includes for each system the files necessary for network and file I/O. It should be used in conjunction with HTUtils.h to help ensure portability across as many platforms and flavors of platforms as possible.
