This is what I'm getting ;

a) Is there any reason why you can't use the current 21.3?
b) Investigate why configure doesn't find strerror() in the system
headers. It does on my machine here, as it should and if it finds
that, it shouldn't try to use it's own version. I admit my machine is
linux-ppc, not i386.
Hope this helps, benny

Hi Benny,
Actually I compiled 21.2 to make sure the problem wasn't
with 21.3 - they both get the same error.
The problem appears to be the stdio.h in /usr/include defines
strerror differently from movemail.c. If I compile without
movemail, it just fails with a similar error on emacsclient.
/usr/include/stdio.h
#ifdef __USE_BSD
extern int sys_nerr;
extern __const char *__const sys_errlist[];
#endif
#ifdef __USE_GNU
extern int _sys_nerr;
extern __const char *__const _sys_errlist[];
#endif
../emacs21.3/lib-src/movemail.c
strerror (errnum)
int errnum;
{
extern char *sys_errlist[];
extern int sys_nerr;
if (errnum >= 0 && errnum < sys_nerr)
return sys_errlist[errnum];
return (char *) "Unknown error";
}

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.
