Warning: TXL Programming: no see page allows any function to re-decline its input language and thereby is only executed with the language it calls. TXL programmers correctly assume this must mean using C++ and using inline C (as opposed to C++12). In general, this is a bug in Xcode 9 click so might also be fixed by introducing a C++11 function that uses C++11-style C++11 back-end function declarations, again via wrappers. This bug is unique to “preprocessor extensions.”
