pragma External ( [ Convention =>] convention_IDENTIFIER, [ Entity =>] LOCAL_NAME [, [External_Name =>] static_string_EXPRESSION ] [, [Link_Name =>] static_string_EXPRESSION ]);
This pragma is identical in syntax and semantics to pragma
Export as defined in the Ada Reference Manual. It is
provided for compatibility with some Ada 83 compilers that
used this pragma for exactly the same purposes as pragma
Export before the latter was standardized.
