I take it you wouldn't advocate removing it outright? What other
options would you suggest (without causing undue confusion to newer
users)?

I'm not sure if there was support for this with the 2.95.3-5 compiler.
Obviously you can't mix the new libstdc++ with the old compiler, so it
might require a compiler upgrade for some people. On the other hand, I
can't imagine that many people would be affected by this (how far back
are we trying to support, anyway). I think it's important not to
confuse new users, who are likely to have (or be able to move to ) a
recent release of Cygwin anyway.

The only correspondence I've ever had about this toolset usually
indicated that it was not very robust anyway (various problems with
the instructions for building STLport).
