You miss the point.  Using -ansi -D_POSIX_SOURCE is the right thing for a
strict POSIX environment, and -ansi -pedantic is the right thing for a
strict ANSI/ISO C environment.  The only problem I had was complaining
about violations of ANSI/ISO C when you used -ansi -D_POSIX_SOURCE; if
ANSI/ISO C compliance is what's being tested, then -ansi -pedantic must be
used.
