Comment(by mloskot <mateusz@…>):

 Following my last comment, here is are minimal programs to reproduce the
 problem using Comeau C/C++ compiler:

  * This version does '''not''' compile

 {{{
 $ cat bad.cpp
 #include <sys/types.h>
 #include <boost/cstdint.hpp>
 int main()
 {
     boost::int64_t a(0);
     return 0;
 }

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

  * This version does compile

 I've also tried to find open GCC bugs related to this issue, but the only
 I found that mentions stdint.h file and preprocessor define ''_ _
 int8_t_defined'' is [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=448 Bug
 448] - <stdint.h>-related issues (C99 issues), however it was reported to
 old GCC 2.96.
