The correct way is to remove all declarations and explicit use of
sys_errlist and sys_nerr and use strerror().  This is a worse way 
if you want a quick and dirty port.

_POSIX_SOURCE is better because ANSI features are a subset of POSIX
features and most programs require POSIX features and BSD extensions.
Using either is bogus because incorrectly declaring features and
extensions doesn't change them.
