My point is that neither movemail nor emacsclient should define
strerror() at all.  It is part of the runtime library and there is no
reason to replace it.  Which is probably why these definitions don't
fit with the runtime definitions, they were never intended to do that.

Both definitions of the function in movemail.c and in emacsclient.c
are surrounded by "#ifndef HAVE_STRERROR".  This define should be set
by the configure script on Linux when it finds the function in the
compiler runtime.

You need to find out, why this doesn't work in your setup, e.g. by
looking at config.log.  You may also be able just to set the define
yourself in some option to temporarily get around this, but that
wouldn't get at the root of the problem.

Hope this helps, benny
