>How-To-Repeat:
./configure --enable-languages=c,c++
make bootstrap
>Fix:
I started with a working gcc 2.96.  3.0.1 didn't bootstrap
until I configured it --disable-shared --enable-languages=c.
Then I tried 3.0.4, same problem, same workaround.
Then I tried 3.1, same problem, same workaround.
Now I'm trying 3.1.1.  I'll try --disable-shared on that.
I really want a working C++, not just C.

I'm having the same sort of problem on Solaris.  Only on 
Solaris the .map file isn't empty; it doesn't parse correctly
for some reason.  Or, depending on configuration, it gets to a
place where it runs ./cc1 .... -o /tmp/xxxx.s and then ld
complains that /tmp/xxxx.s is an unknown file type and
isn't a valid linker command script.  Very strange.
