If I were asked directly about that patch, I would have
explained it. But I thought it was quite obvious that
--enable-shared would include the seond config file on
many platforms.

One more thing, will there be a libstdc++ 2.8 for gcc
2.8? If the answer is yes, $(CC) should be used for
making libstdc++.so in libstdc++/Makefile.in, instead
of $(CXX).

I am not sure if it is a good idea. I tend to think it may
cause more trouble than my old patch. The problem happens
when you have more than one config files. In my case, it
is --enable-shared. You don't want linuxpic if --enable-shared
is not used. To do it right, you should support multiple
config files.

BTW, if you take time to have a close look at my patch, you
may find it quite reasonable. My patch just allows multiple
config files.
