OK, good.

[snipped]

I'm not sure that I can patch all of those, but I'll look into it.

OK, that's good: the error's are only comming from the RegEx class (which is
depecated anyway), and not the underlying template code, actually it looks
to me like this may be an error in the test suite rather than the library
itself.

I'll see if I can scope any obvious integer overflows and the like.

BTW, I have access to aCC now thanks to HP's testdrive program, and the
current cvs source compiles and runs with no issues/errors you'll be pleased
to know.

Thanks,

John.
