can you try to re-install libstdc++6 ?

Hmm, here's a problem:
$ cygcheck -f /usr/bin/cygstdc++-6.dll
libstdc++6-7.4.0-1
This is after doing a reinstall selecting 10.2.0-1 (twice!). Setup
thinks I have 10.2.0-1 installed (i.e. that's what is displayed as
current in the GUI), but /etc/setup/installed.db says:
$ grep stdc /etc/setup/installed.db
libstdc++6 libstdc++6-7.4.0-1.tar.bz2 0
Hmmm. I've been using a scripted setup procedure that automatically
downloads the setup program and then starts it with specific arguments.
For some reason that did not do what I thought it was doing (or what
*it* thought it was doing).
I did it manually, and low and behold, many packages needed to be updated.
And now everything seems to be behaving as it ought to.
Thanks all for all suggestions offered!
