[Rafal Dabrowa <rafal@softsystem.com.pl>] libc/1163: glibc: wrong work of strcoll

[Andreas Jaeger <aj@arthur.rhein-neckar.de>]

What's broken here (i486, glibc 2.1.1)?

Without any locale information:
$  ./strcoll-test a B; ./strcoll-test B b
strcoll( a, B ) = 31
strcoll( B, b ) = -32

with LANG=de_DE (locale is installed)
$ LANG=de_DE ./strcoll-test a B; LANG=de_DE ./strcoll-test B b 
strcoll( a, B ) = -1
strcoll( B, b ) = 1

with LANG=pl_PL (generated with: localedef -i pl_PL -f ISO-8859-2 pl_PL)
$ LANG=pl_PL ./strcoll-test a B; LANG=pl_PL ./strcoll-test B b
strcoll( a, B ) = -1
strcoll( B, b ) = 1

>Description:
	after call setlocale(LC_ALL, ""), function strcoll
	produces wrong results. e.g.:
	strcoll( "a", "B" ) = -1		(should be greater than 0)
	strcoll( "B", "b" ) = 1			(should be less than 0)
>How-To-Repeat:
	please compile program below:

		#include <stdio.h>
		#include <string.h>
		#include <locale.h>

		int main( int argc, char *argv[])
		{
			setlocale(LC_ALL, "" );
			printf( "strcoll( %s, %s ) = %d\n",
				argv[1], argv[2], strcoll(argv[1], argv[2]) );
			return 0;
		}
	and run it - e.g.:
		a.out a B
		a.out B b
	I have set LANG to "pl" and LC_ALL to "pl_PL"; but I checked it also
	with LANG set to "en" and LC_ALL equal "en_US" - there are similar errors.
