                                  clang::PragmaIntroducerKind Introducer,

  // Pragma in ACC should be a name/value pair

  if (GetPragmaNameFromToken(FirstToken, PragmaName)) {
    // start parsing the value '(' PragmaValue ')', if we have one.
    const clang::Token* NextToken = &PP.LookAhead(0);

    if (NextToken->is(clang::tok::l_paren))
      PP.LexUnexpandedToken(CurrentToken);

 end_parsing_pragma_value:

  // PragmaValue may be an empty string.
  mPragmas->push_back(make_pair(PragmaName, PragmaValue));

  // Inform lex to eat the token
  PP.LexUnexpandedToken(CurrentToken);
