Subject: Mark the return value from strerror as a constant
X-Git-Tag: emacs-28.0.90~5643
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=14e00d95c4edb724bd12357e37dd443d785c1170;p=emacs.git

Mark the return value from strerror as a constant

* src/emacs.c (main): Mark the return from strerror as a constant,
since it shouldn't be changed (bug#43982).

* lib-src/movemail.c (pfatal_and_delete): Ditto.
