Yes, that's what I mean with:

      I know the ISO C++ 1998 standard introduced a heavy use of
     templates in the C++ standard library  and is one of the reasons for
     the
     increase in code size and compilation time.

     it should come as no surprise that full support for it
     comes at a price.

     A much better comparison would be with a C program, not a C++ program.

Yes, that's the case of BYTE tests.
In my case, the editor, none of the code involved in the meassurement I did
involves C++ standard library.
Is my formating code (for syntax highlight) blitting lines to the screen.
