>Description:
Compiling the one line C++ source file using g++:

inline const long and(const long L, const long R) { return (L && R); }

produces the error message:

1: parse error before `&&' token

This code compiles fine with gcc-3.1.1 (C), gcc-2.95.3 (C), g++-2.95.3 (C++), MS Visual C++ (C/C++).
>How-To-Repeat:
Compile the following source using g++:

inline const long and(const long L, const long R) { return (L && R); }
