The sun c++ compiler doesn't issue a warning about comparison between 
signed and unsigned integer expressions.
The attached patch makes mpl::print produce "implicit int is not 
supported" warning.

With the patch applied the compiler output looks like this:
$ CC +w -c print.cpp
"/home/dgoncharov/boost/trunk/boost/mpl/print.hpp", line 55: Warning: 
Implicit int is not supported in C++.
"print.cpp", line 3:     Where: While specializing "boost::mpl::print<int>".
"print.cpp", line 3:     Where: Specialized in non-template code.
1 Warning(s) detected.
