PR: 338 Here's the description, submitted by Gisle Vanem <giva@bgnett.no>: 1. sock_init() renamed to ssl_sock_init() in ./apps/s_socket.c due to name-clash with Watt-32. 2. rand() renamed to Rand() in ./crypto/bn/divtest.c due to name-clash with <stdlib.h> 3. Added calls to dbug_init()/sock_init() in some demo programs. 4. Changed cflags/lflags in configure. Watt-32 install root now taken from $WATT_ROOT.
