We found an issue with paths that -start- with a '-', there are apparently many 
places where paths are passed into various shell, and the initial '-' can be 
read as an argument identifier.

I don't believe Qi Chen sent it to the list, but we built path names with all of 
the special characters and tried to run builds.  The specific list is based on 
the results of those tests.  The other items are already broken, and we're 
trying to be explicit with this for end users.  (Note, it's really the TMPDIR 
that matters.. the 'build' directory is a lot more flexible.)
