1) Disabled recursive implementation for VC8: stack overflows can't be reliably detected unless the whole program is compiled with asynchronous exceptions.

Browse Source 
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.
