I'm trying to get spirit parser to compile in aC++, but aC++ errors on the following line. The problem apparently is that aC++ is not recognizing extract_int_ as a type, so a preceding typename keyword is required for it to compile. Hoping to get instruction on how to change this so that it won't break other compilers? Thanks! boost/spirit/core/primitives/impl/numerics.ipp:305 return extract_int_<(MaxDigits >= 0)>::template apply<Radix, MinDigits, MaxDigits, Accumulate>:: f(scan, n, count); fixed for aC++ is as follows, but may break other compilers??: return typename extract_int_<(MaxDigits >= 0)>::template apply<Radix, MinDigits, MaxDigits, Accumulate>:: f(scan, n, count); -Jerry
