Well, of course I installed the whole package that
the zip picker recommended. I am not enough of an
expert on gcc to be brave enough to just install part
of it over an old version. In particular I got
gcc2952b.zip as well.

Yes, the slow part is CC1PLUS.
And, no, the program does not run any faster.
It is about 0.5% larger and about 1% slower.

Well, if one of my programs suddenly went from 23 seconds
to 32 seconds you can be sure I would investigate it, and fix it.
