Why are you specifying a standard and then using features outside its
scope?  Either you want a BSD environment (in which case don't specify
a standard), or you want a standard environment (where file.h doesn't
exist).  Indeed what you are trying to do is unsupported.

For details on how to write a conforming application see section 2.2
of POSIX.1-2001.
