If I understand things correctly, the install.log file is not
intended to catch errors.  It just grabs output from tar so
that an uninstall script can be created.

Care to submit a patch?

Corinna had already noted these errors and is tracking down the cause.
I hope.

/usr/lib is a "symbolic link" to /lib.  See previous voluminous
discussions about this in the cygwin-developers mailing list.

How about installing from the Internet?  It sounds like your gdb.tar.gz
file might have been corrupted.

Or, patch the installer to do the right thing.  Care to take a stab at
this?  I don't know why extracting things here would present a problem,
offhand.

Since the install.log file is used for something else, I'm not sure that
that's a good idea.  I'll look at the source code and see if errors can
be filtered out while the log file is being processed.

Please!

I don't know.  "bootstrap" may not be as clear to a non-technical user.
I am open to a vote on the subject, though.
