Assuming you really made a mess (while problem could be just minor),
I suggest to remove everything without version numbers:
rm libstdc++.so libstdc++.a libstdc++.la

This should result in the linker error: can find -lstdc++
or something like that.

The files with version numbers are only used when *running* a program,
so you might want to keep them or else you might break installed
applications (you can savely remove those that are installed after
you started to try to fix things though).

The first is used by g++ versions 2.95.x, the latter by 3.x.

For now, assume that the compiler version and libstdc++ version belong
to eachother: you don't want to mix those.

As of 2.95.x (at least, as far as I know), libstdc++ is part of the gcc
package.  All you need to do is to install 'gcc' (with C++ support) and
everything should be fixed.

libstdc++-2.92.2 belongs to gcc-3.x.  That is why this won't work.

Look again on the GNU ftp sites where you found gcc-2.95.3, it contains
a tar.gz that contains EVERYTHING, *or* you can choose to download
multiple tar files (a common, a part with C++ support, java,.. fortran etc).
If you just got the common part then you just had a C compiler.  Adding
an arbitrary libstdc++ from somewhere else doesn't work: you should get
the tar gcc-g++.2.95.3.tar.gz or something. That contains the correct
libstdc++.
