Comment(by mloskot <mateusz@…>):

 I think I have managed to reproduce the problem with minimal program. I'm
 not sure where is the problem, either in Boost.Integer or
 [http://www.comeaucomputing.com/libcomo/36.html libcomo36] I use with my
 installation of Comeau C/C++ compiler.

  * Simple test which '''do not''' compile

 {{{
 $ cat cstdint.cpp
 #include <iostream>
 #include <boost/cstdint.hpp>
 int main()
 {
     boost::int64_t i64 = -2;
     boost::uint64_t ui64 = 2;
     boost::uint64_t d = ui64 - i64;
     std::cout << d << std::endl;
     return 0;
 }

 $ como -I/home/mloskot/dev/boost/_svn/trunk cstdint.cpp

 }}}

  * The same simple test but with ''#include'' directives reordered and now
 it '''does''' compile

 {{{
 $ cat cstdint.cpp
 #include <boost/cstdint.hpp>
 #include <iostream>
 int main()
 {
     boost::int64_t i64 = -2;
     boost::uint64_t ui64 = 2;
     boost::uint64_t d = ui64 - i64;
     std::cout << d << std::endl;
     return 0;
 }

 $ como -I/home/mloskot/dev/boost/_svn/trunk cstdint.cpp

 $ ./a.out

 I'd appreciate if somebody could confirm if this is Boost problem or not.
