hi todd,


thanks for the new gcc libs.  just one problem:  the libio & _G_config.h
headers aren't installed currently.  i've modified my tree to:

	- output LIBIO_HEADERS from toolchain2netbsd
	- re-add the `io' and `config' dirs in gnu/lib/libstdc++
	- modify the above to deal with USE_NEW_TOOLCHAIN.

it seems to work fine.  however, i wonder if you were thinking of doing
the _G_config.h idea another way.

(i attempted to place the libio headers in libstdc++/include, but that
requires the .PATH that breaks that being in libstdc++/. itself, so i
reverted back to using the libstdc++/io directory.  perhaps we could
move the std & stl headers back into these dirs as well?  dunno.)


what do you think?
