インテル® Fortran コンパイラー 14.0 ユーザー・リファレンス・ガイド
The ATTRIBUTES directive option DECORATE specifies that the external name used in !DIR$ ALIAS or !DIR$ ATTRIBUTES ALIAS should have the prefix and postfix decorations performed on it that are associated with the platform and calling mechanism that is in effect. These are the same decorations performed on the procedure name when ALIAS is not specified, except that, on Linux* and OS X* systems, DECORATE does not add a trailing underscore signifying a Fortran procedure.
