Not as bad, but still pretty awful:

$ /scribble/phil/gcc/install/bin/g++ -v
Using built-in specs.
Configured with: ../gcc/configure --prefix=/scribble/phil/gcc/install
--disable-checking --enable-languages=c++
Thread model: posix
gcc version 4.0.0 20050114 (experimental)
$ time /scribble/phil/gcc/install/bin/g++ -O -c
list1.cpp

real    0m1.758s
user    0m1.677s
sys     0m0.035s
$ time gcc-3.4 -O -c list1.cpp

real    0m0.101s
user    0m0.069s
sys     0m0.009s

cheers, Phil
