[Boost-users] [Wave] error: ill-formed directive

Using the 'samples/cpp_tokens' example preprocessor with the following code: #define true 1 #define false 0 gives the following error: test.C(1): error: ill formed preprocessor directive: #define Preprocessing the same file with 'cpp' give no error. If any of the two lines in the file is removed the other line will cause an error. I guess the error occurs because 'true' is not an T_IDENTIFIER, but a T_TRUE. Could you imagine a clean fix to this issue? Regards. Andreas
