string algorithms is currently failing all tests on all platforms on CVS HEAD. AFAICT, the problem is that the string algo tests call the range library begin/end functions with raw character pointers, I guess looking for this to turn into a range by use of strlen or similar. The range library flags a compile failure trying to form C::const_iterator where C -> char *. I also see the range library has appropriate overloads for fixed-length arrays, and does not handle arrays of unknown size. I don't know if these fails are due to changes in the range library or string algorithms, so I'm not sure what to suggest as a patch yet. Any comments from the library authors appreciated (even if it is simply pointing to a previous discussion I have missed) -- AlisdairM
