Hello, I found a problem with preprocessing "/##/" macro. For example, I have a next code: #define COMMENT_MACRO /##/ void test() { COMMENT_MACRO comment } This code can pe preprocessed (with help any correct preprocessor) to next: void test() { // comment } But after usage boost::wave utility (from boost 1.43) I have this code: void test() { comment } How you see the symbol "//" is forgotten. How fix it?
