for building code that references the networking API. It is now possible, provided you build your code with an existing TCP/IP API header file set (such as from the "Roadshow" SDK) without running into data type or function prototype declaration conflicts. I have added local versions of <arpa/inet.h>, <netinet/in.h>, <netdb.h>, <sys/filio.h>, <sys/ioccom.h>, <sys/ioctl.h>, <sys/select.h> and <sys/socket.h> and updated <unistd.h>, <pwd.h> and <grp.h> accordingly. Note that some of the function prototypes will conflict with the bsdsocket.library/usergroup.library API, which is why you can disable the declarations through the __NO_NET_API preprocessor symbol: if defined, none of the function prototypes will be defined. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@15036 87f5fb63-7c3d-0410-a384-fd976d0f7a62
