Some problems with gcc-2.97 20010108

Here is output of gcc -v -c ... with some comments:

Why line about version of GNU CPP is outputted twice?

I put binaries at directory different from prefix used at configure time
(default /usr/local for configure, installed at /disk2/gcctest)
GCC looks for include files in $prefix/$target/include/g++-v3 (doesn't exist),
but not /disk2/gcctest/i686-pc-linux-gnu/include/g++-v3.
So getting real prefix from actual location of gcc binary is broken.
