Re: environ is autofiltered from dll export list?

Actually, it really suggests that "cygwin_premain" should be in the prefix list. The others should probably move to the symbol list as you suggest.

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:

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