I'll admit this is a bit over my head.  We just ran into this again,
though, so would you mind having a look?

To be clear, /www/gcc/htdocs-preformatted (the raw checkout from git)
features -rw-r--r-- for most files which seems to be fine, though, and
does not cause problems.  It's the pre-processed web tree under
/www/gcc/htdocs where this hits.  

Maybe setting a more permissive umask before invoking 
/www/gcc/bin/preprocess is the best approach?
