Attached with startup environment, locale, and message setup cut (reduced by
100KB), and rest sanitized as below. Could DM/PM original on request.

Sanitized with a script I use on posted output in case I forget to use aliases
like llgo (ls -lgo).
Created the script for cygcheck -hrsv output in case I forget, now run from
permanent postinstall script in background, as it takes a while if needed, and
my desktop environments are messy with stuff from ~/.bash_... setup scripts.
