C++11 preprocessor syntax not supported

[Bertk]

See Replacing text macros syntax 4

define identifier( ... ) replacement-list

CXX Plug-in fails with syntax 4 – sample code:

#define showlist(...) puts(#__VA_ARGS__)
showlist(1, "x", int); // expands to puts("1, \"x\", int")
showlist("x");         // expands to puts("\"x\"")
showlist();            // expands to puts("")

SSLR toolkit output:

com.sonar.sslr.api.RecognitionException: Parse error at line 4 column 10:

    2: puts ( "1,\"x\",int" );
    3: puts ( "\"x\"" );
  -->  puts (    ;
    5: 
    6: EOF
