For the record: I have been testing a macro pointing getenv at an
alternate implementation for the purpose of my port.  This alternate
function will return a unique pointer for each variable, as opposed to
using the same static buffer.  IBM considers this function a
proprietary z/OS extension (whereas the other is labelled as
conforming to half a dozen standards), but it seems to be more in-line
with the behavior git expects.

So I agree this patch is useful for reaching strict conformance to the
published specs, but I think we can go back to assuming no known
platforms are broken and unusable because of this.
