I have now tested the conversions of all libc error strings in all
locales in glibc 2.1.92, and I find no examples where my method
gives another result than if LC_CTYPE was permanently set.
Could you please say where you think that my method can give bad
transliterations?

Well, I will then add a configure test for nl_langinfo(CODESET).
My test programs and test results:
$ cat test_method_1.c
#include <errno.h>
#include <locale.h>
#include <libintl.h>
#include <langinfo.h>
#include <stdio.h>
#include <string.h>
int main ()
{
int i;
extern int sys_nerr;
setlocale (LC_CTYPE, "");
bind_textdomain_codeset ("libc", nl_langinfo(CODESET));
setlocale (LC_CTYPE, "C");
for (i = 1 ; i < sys_nerr ; i ++)
puts (strerror (i));
return 0;
}
$ cat test_method_2.c
#include <errno.h>
#include <locale.h>
#include <stdio.h>
#include <string.h>
int main ()
{
int i;
extern int sys_nerr;
setlocale (LC_CTYPE, "");
for (i = 1 ; i < sys_nerr ; i ++)
puts (strerror (i));
return 0;
}
$ cat test_conversion.c
#include <sys/types.h>
#include <dirent.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
int main ()
{
DIR *dir;
struct dirent *dirent;
char cmd[80];
unsetenv ("LANG");
unsetenv ("LANGUAGE");
unsetenv ("LC_ALL");
unsetenv ("LC_CTYPE");
unsetenv ("LC_MESSAGES");
dir = opendir ("/usr/share/locale");
while ((dirent = readdir (dir)))
{
if (strcmp (dirent->d_name, "locale.alias") == 0 ||
strcmp (dirent->d_name, ".") == 0 ||
strcmp (dirent->d_name, "..") == 0)
continue;
printf ("testing locale %s... ", dirent->d_name);
setenv ("LC_ALL", dirent->d_name, 1);
sprintf (cmd, "./test_method_1 > test-%s-1.out", dirent->d_name);
system (cmd);
sprintf (cmd, "./test_method_2 > test-%s-2.out", dirent->d_name);
system (cmd);
sprintf (cmd, "cmp -s test-%s-1.out test-%s-2.out",
dirent->d_name, dirent->d_name);
switch (system (cmd))
{
case 0:
printf ("OK\n");
break;
case 1:
printf ("FAIL - the conversions are different\n");
break;
default:
printf ("Error calling cmp\n");
break;
}
}
return 0;
