I can't think of any Ada compiler that went that far, though.  All
"extensions" I'm aware of have either been domain-oriented packages
(encouraged by the standard), or implementation-defined pragmas
(allowed by the language).  DEC Ada featured mostly the former in its
Starlet package that enabled access to OS facilities, much as the
POSIX/Ada binding enabled access to POSIX compliant OS's.
