`environ' is a symbol that comes from the library.  It is a pointer to
an array of char *, where each array element is a string of the form
"foo=bar": these are the environment variables and their values.

I guess if this happens even under "-ansi -pedantic", it's a bug that
we pollute the ANSI namespace with a non-ANSI symbol that doesn't bgin
with an underscore.  But given that Unix programs expect that symbol,
I'm not sure we can change that.
