Yeah, that's true.  A double-extern really isn't a big deal if it's 
declared the same way in both places, and I wouldn't imagine environ to 
ever be anything but a char**.  But I'd rather be safe.  You can do a 
test for it in configure.ac in just a few lines.

Sadly environ is 'special' -- there's a long crappy history of it not 
being declared in header files and needing to be declared manually.
