c++ example

[Даниил Яицков]

I have a problem with compilation of calculator on C++ language. I use 
Linux (Slackware 11) and GCC 3.4.6.
I taken example from Info-Help, wrote makefile. All program files base 
on Info-Help. The log of compilation is in log file. There is one same 
error. I guess that template class messages from standard library c++ 
use parameter type which not support some operations. But sources of 
program not use this class explicitly. I don't know, what i must do.
All main files enclosed.
