Re: configure doesn't work today

You can still build with this, even though it looks frightening.

config-ml.in is needed to make multilibs work. This file is in the 
top-level gcc distro... 

The end result is that I'd like to move libstdc++-v3 from being a 
"stand-alone" project that one can download and build without any other 
tweaking to something that relies on an existing gcc source directory. 
Yes this is a pain, but doing this allows v-3 to do things like build 
multi-libs, and work with cross compilers. FWIW, this functionality is 
necessary for v-3 to replace v-2.

The end goal is to have v-3 be more of a "plug-in" replacement for the 
current v-2 distro. You'll need to re-arrange your source and build 
trees a bit because of this:

1) get the gcc-2.95.2 distro
2) unpack
3) cd gcc-2.95.2; mv libstdc++ libstdc++-v2
4) copy over your libstdc++-v3 sources to the gcc-2.95.2 toplevel source dir.
   ie 
   cd ..
   cp -R libstdc++ gcc-2.95.2/libstdc++-v3
5) link correct library sources to "libstd++"
   ie
   cd gcc-2.95.2
   ln -s libstdc++-v3 libstdc++

You'll now be able to build just the library, but will need to 
re-configure with this new info

I know this is a pain.
