  Well I have access to one DU machine and I tested this code there
and it worked. I'm pretty sure I used the native C compiler and not gcc.

  Note taht is you don't use socklen_t on DU you may end-up with serious
aligment problems since the POSIX system call expects a pointer to a
64bits area while you're passing a pointer to a 32bit area with int* ...
