/*
 * Linux specific socket include
 *
 * Under Linux if we dont define _POSIX_C_SOURCE or _XOPEN_SOURCE
 * then none of the POSIX stuff (such as signals) can be used
 * with cc -v. However if one of _POSIX_C_SOURCE or _XOPEN_SOURCE
 * are defined then we cant use the socket library. Therefore I 
 * have been adding the following in order to use POSIX signals 
 * and also sockets on Linux with cc -v. What a pain....
