Subject: [gfortran] PATCH PR20480 zero is written with non-zero exponent

Hi all,

This patch fixes PR libfortran/20480 (writing zero with ES format) and
another similar case I don't think has been reported (same thing with EN
format). As far as I can tell, those are the only cases left when we
could write 0.0 with a non-zero exponent.

*strapped and regtested on i686-linux for mainline. *strapped and testing
in progress on 4.0. OK for both branches (after regtesting completes on
4.0) with the attached testcase?


PS: unlike my previous patchs, this time I do have my copyright
assignment done and I do have CVS write access. Things are getting
better!
