 As i see it  u declared something that is declared in some other place, the
solution is:
Change the name of  the duplicate identifier

Actually this one is hard ( I've used to Borland C++ so the error messages of
gcc are new for me) but I think that commanting out sys_errlist produced this,
you should check where else is sys_errlist declared (use grep an a lot of
pacience.
 That's my best
