When I first started trying to support aCC with Boost that was a common issue. Most of them were ferreted out. I don't think anybody is actively looking at that compiler, perhaps Jens Maurer still is. Anyway, the proper solution is to name the template parameter, your option 2. I've cc'ed Bill Kempf in case he doesn't follow this list.

In boost/function/function_base.hpp the compiler give us this error: Error 20: "function_base.hpp", line 37 # '<type name>' expected before '>'. template<bool> struct truth {}; We are using Boost 1.28.0. The line 37 in function_base.hpp has: template<bool> struct truth {}; We have found two ways to make it work: 1.- Comment out the line !! 2.- Replace with: template<bool a> struct truth {}; We think that the compiler is wrong but, is ok to comment this line? In earlier versions of this file this line doesn't exists, and it is never used, so it is necesary? Regards, Raúl.
