Neither POSIX.1 or POSIX.2 require a (complete) ANSI/ISO C library or
an ANSI/ISO C compiler.  The later is only an option in .2.

POSIX requires the ANSI/ISO C library and I think it requires an ANSI/ISO C
compiler to be available. However not all older unix systems are POSIX
compilent. I am not aware if it is intended to require that UNIX should have
ANSI/ISO C++ as a prerequisite when it becomes available.

As you know, there are many difference between UNIX C(++) and
ANSI C(++). Some of the library functions like 'strtoul' is defined
in ANSI C, but not in UNIX C. This may be because the history reason.
While UXIX C++ appear, why don't they introduce more library functions
to make UNIX C++ compiler to be more close to ANSI standard???
