The value of this option should specify the full pathname of the C/C++ Front

End to be used. If this option is not provided, the PATH will be searched for
|
||||||
|
a program named <i>llvm-gcc</i> and the C/C++ FrontEnd install directory will
|
||||||
|
be inferred from the path found. If the option is not given, and no llvm-gcc

can be found in the path then a warning will be produced by
