Having gotten this installed, and having removed GCC 2.953, I have
recompiled a few things unchanged, and am observing the following:

1) It is showing up failure to #include <string.h> here and there
when using strlen and strcmp.  Good.

2) The executables are a little bit smaller, compiled with
gstabs+.  However after passing through strip the executables are
somewhat larger.  Don't know why.

3) All versions were compiled with O2.  Looking at the generated
code with "objdump -dS" it appears as if the optimization is quite
different.  Many lumps seem to be relegated to "final" code
outside the purvey of the source.  This may be related to 2)

These are just observations.  None of them seem to be critical.
