GCC 4.5 does not have full support for C++0x.  We'll need an upgrade to
4.7 for this to work.


That's surprising. The regex header was in TR1, from back in 2005. I'd
have expected gcc to support it a long time ago. I'm also surprised to
see that the header definition present and the libstdc++ implementation
absent. That's what made me think there was something wrong with the
toolchain.

Thanks.



std::regex is not fully implemented; upgrading to GCC 4.7 won't change 
anything. there are several todo notices in regex header files hinting 
at this.


have a look at boost::regex for the time being; should be close enough 
to std::regex.
