2003-04-26 - _GLIBCPP_HAS_BUILTIN_SINF: We should still hold out for a cleaner solution the is currenly the case in bits/std_cmath.h. - there may be one set of remaining string bugs, dependent on final clarification of the string::find technicalities when finding in an empty string or using an empty string for an argument. At the very least, v-3 has interpreted the standard in a way that is in opposition to other libraries on other platforms. - trigraphs and keywords a la the iso646 header are not correctly implemented. It looks like the compiler recognizes them as keywords but then doesn't translate into the correct bit ops. It is a mystery. - wide strings have not been tested, and may therefore be unusable. - Chapter 27 io functionality is not finished. As such, there are known bugs in: filebuf::putbackfail - Many facet implementations are stubs. (22) - Almost no optimizations for small-footprint/low-overhead. (22,27) - There has been some work to wrap the C headers in namespace std::, but it may not be complete yet, and C macros are not shadowed. Please consult the mailing list archives for more information.
