2) Changed std::copy calls on VC8 to avoid "dangerous code" warnings. 3) Moved backreference and octal escape code into line with POSIX-extended requirements. 4) Changed match_results leftmost-longest rules to stop unnecessary std::distance computations (an optimisation for non-random access iterators). 5) Changed C lib calls to use "safe" versions of string API's where available. 6) Added many new POSIX-extended leftmost-longest tests, to verify the above.
