Ah, it is the std::wstring. Some of the windows ports of gcc to windows are
missing the wide character stuff from the standard C++ library. You can
maybe get it working by adding a #ifdef around the offending bits of code to
disable them when they are used on the version of gcc used by cygwin 1.5.
Or you could try using mingw. I believe it's newest version isn't missing
these things from its library.
I'll play around with cygwin when I get some free time and see if I can't
find a workaround. But let me know if you find an easy solution :)
