We are currently compiling using the GNU C++ lib option using QCC -V4.2.1,gcc_ntoshle_gpp
and want to move over to building an ISO compliant build.

From the documentation it looks like one simply removes the _gpp extention and calls QCC -V4.2.1,gcc_ntoshle to use the 
Dinkum C++ lib

Is this the only step required to build our app. conforming to the ISO standards?
