Maybe.  But this info is redundant: the memory dump already has it.

Also, I don't understand why is it so important to have environ[] stashed 
away separately.  How is it different from any other global variable used 
internally by the library?

Well, I've seen all this even without CScope, except that I was looking 
inside GDB and so didn't see binutils/size.c; thanks.

FWIW, it looks like GDB itself never uses the info in this field; Cygwin 
doesn't even compute it, probably for that same reason.
