`make install' won't clean up the g++-include directory, because it
might contain something useful.

But include-files are not libraries, right? :-)

I guess it is searched by default.  Run `g++ -E -v - < /dev/null' to
check what the search path is.

You may want to configure
--with-gxx-include-dir=/usr/local/include/eg++-1.1 or
--with-local-prefix=/usr/local/egcs or even with
--prefix=/usr/local/egcs-1.1

I'm not sure which one will fix your problem, but one of them should
do it, but each one will have different side-effects.  I myself prefer
to install each package in a separate directory, so I'd use the last
option.  However, this may not eliminate the possibility of having
/usr/local/lib/g++-include installed in the search path :-(
