Sure.  Because the language handled by 2.95.3 is not C++ as defined by
the Standard; streams, templates, and a lot of other things.

If you want speed, switch to C.

If you want C++, leave 2.95; if you want C++ with faster executables
and some compiler slowdown, switch to 3.4.6; if you want a fast
compiler and a fast executable, switch to 4.1.0 .
