I don't have access to Comeau C++ so I can't test how it behaves in its
various modes. I assumed that when _MSC_VER is defined, then the compiler is
in MSVC compatibility mode. Are you saying that in strict mode _MSC_VER is
still defined, but the void returns work? If so, can you post a patch to
boost/config/compiler/comeau.hpp?

Also, did you try to run Comeau in MSVC 7 mode? I'm fairly certain that void
returns work. The option was --microsoft-ver=1300 IIRC but I may be wrong.

(The void returns path is problematic in general. It works on MSVC 6 and on
EDG 2.38 (?) but few other compilers can cope.)
