You are mixing versions of gcc and libstdc++ and libg++. My 
experience shows that it is Ok for C but not for C++ (!!!!)

e.g. using libstdc++-2.8.1.1 or libg++-2.8.1.1 with gcc-2.7.2.1.
The same problem will be when port of egcs-1.1 will be released
(perhaps when DJGPP-2.02 will be released).

So ALL C++ sources MUST be compiled with the same version of 
gcc (even mixing gcc-2.8.0 and gcc-2.8.1 is not Ok as shows my 
experience)
