For those who came in late,  I found some code that reported errors by nu=
mber=20
and changed it to use strerrno() and fprintf() (or some such) and then go=
t=20
some bizarre error.

I reported it to the list, and Jeff said, "Happened to me too."

The rough and ready workaround is
[summer@possum summer]$ perror 2
errno 2 =3D No such file or directory
[summer@possum summer]$ +

and the source code for perror is
[uml@dugite uml]$ cat /home/summer/src/perror.c
#include <errno.h>
#include <stdlib.h>
#include <stdio.h>
=20
int main(int argc, char *argv[], char * environ[])
        {
    int eno;
    if (argc !=3D 2) {
        fprintf(stderr, "Usage:  %s <errno>\n", argv[0]);
        exit(-1);
    }
    eno =3D atoi(argv[1]);
    printf("errno %d =3D %s\n", eno, strerror(eno));
    return 0;
};
