Most DEC compilers extend the underlying langauge to make it usable for
system programming and comply with the requirements of various U.S.
government standards that extend the ANSI and ISO language standards.

All DEC compilers which I have seen that extend a language have a
switch ( usually /STANDARD) which causes the compiler to treat these
extensions as (minor) errors and inform the user.  People writing
portable code should always specify such a flag.  Failing to do so is
like not 'lint'-ing one's C programs under Unix if you plan to port
them elsewhere.
