- Added h_strerror() function to libnet.a; there's a global 'h_errno' variable available, too. - <signal.h> now defines a type 'sig_t'. - <unistd.h> now allows the 'fd_set' type to be referenced as 'struct fd_set', too. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14690 87f5fb63-7c3d-0410-a384-fd976d0f7a62
