Problems using libstdc++ on LinuxPPC 2000

[Paul Marquis]

When I try bootstrapping CVS gcc on LinuxPPC 2000 (as of 6/13/2000,
8:00 PM, EDT), I get the following error:

Any clues?

BTW, I could never get gcc-2.95.2 bootstrapped with libstdc++-2.90.8,
but I did manage to get it to work by jumping through the following
hoops:

- build and install stock gcc-2.95.2
- rename libio and libstdc++ and install libstdc++-2.90.8 into the gcc
source tree
- configure and install libstdc++ only into a separate area
(/usr/local/lib3)
- add include and lib flags when compiling files that need libstdc++

This is similar to the instructions to pre 2.90.8.
