Well, the way configure works is that it tries to compile little test
programs. So if a compile fails, it throws one of those cryptic
messages you saw. The message is often not related to the file at hand....
I went through the libstdc++-v3/config.log and it basically said all
the same stuff as i posted previously. I'll post a little of it below:

************* here's your actual error *****************
The build chain cannot find those two files. Fix that and the other
problems will most likely go away.
That points to a broken toolchain, so you may be right....
