Ok, I can provide a patch for that, but I would like to understand the 
environ part of my question first.

I think this was needed when there was no auto-importing, and cygwin 
defined environ as __cygwin_environ:
http://www.zsh.org/mla/workers/2000/msg03158.html

Is it still needed? In that case I will have to conditionally compile 
out that part for arm-wince-pe target.
