What is the perl format and best regular expression library that compile in MS VC++6.0?

I wrote a program in c++ in VC++2008 wi开发者_运维问答th boost library for regular expression. But my code must be compiled in vc++6.0 compiler. vc++6 has compile error when using regular expression(I'm not actually sure but I can't compile boostRegex in vc++6). So, for changing my library from boost, what is your opinion to me(one that is more similar to boost regex is better, for decreasing cost of converting. )

Boost 1.34.1 is supposedly the last version which supports VC6, and includes the regex lib. Likely it'd be be easier to revert to that version than switch to a completely different library.
