-G++ does not do name mangling in the same way as other C++
-compilers.  This means that object files compiled with one compiler
-cannot be used with another.
+On many platforms, GCC supports a different ABI for C++ than do other
+compilers, so the object files compiled by GCC cannot be used with object
+files generated by another C++ compiler.
 
-This effect is intentional, to protect you from more subtle problems.
+An area where the difference is most apparent is name mangling.  The use

 Compilers differ as to many internal details of C++ implementation,
 including: how class instances are laid out, how multiple inheritance is
 implemented, and how virtual function calls are handled.  If the name
