When compiling the example programs for dynamic_bitset with MSVC++ 8.0, I get the following message: C:\Program Files\Microsoft Visual Studio 8\VC\INCLUDE\xutility(2841) : warning C4996: 'std::_Fill_n' was declared deprecated and an exhortation to use the "Safe Standard C++ Library". As my first task as dynamic_bitset's maintainer, I want to modify it to not trigger this warning. Unfortunately, unlike most of the other functions that trigger this warning which have _s alternatives, the only alternative to std::fill_n I could find is MS's "safe" version in their standard library extension. There's a preprocessor switch I can set, (_CRT_SECURE_NO_DEPRECATE) but I believe it has to be set globally, as it seemed to have no effect when I included it in dynamic_bitset.hpp. Does this affect any other libraries? Am I missing anything? What is the best way to solve this? Frederick Akalin
