Hi all, I've just uploaded a new version of the Wave preprocesor library (V1.1.4) to the yahoo files section here: http://tinyurl.com/yul67. The same version is checked into the boost-sandbox CVS. There were a lot of changes recently: - Adjusted to use the new version of the program_options library. - Fixed a bunch of minor bugs in the expression evaluation engine. - Made a lot of other rather unrelated bug fixes (see in the ChangeLog file contained inside the distribution). Besides passing its own test suite Wave now passes 98% of the preprocessor validation suite published here: http://tinyurl.com/yul67. The remaining open issues are in the field of wide character and multibyte character handling, which are implementation depended anyway. But I'm still working hard on fixing the remaining issues. Regards Hartmut
