Wow, that is a very well described change.

Additionally two things are lacking explanation in the proposed log
message, though, or an uninitiated will still be left scratching his
head:

 - Why didn't the original need "cygpath -au"?

 - Even though many steps in this job deals with different
   env.COVERITY_PLATFORM, this part does not seem to be conditional.
   Why is $(cygpath -au ...) safe outside Windows environment?

Other than that, nicely done and very nicely explained.
