There seems to be a collation bug.  Here's a test case, extracted from 
the emacs test suite:

$ cat collation_test.c
#include <wchar.h>
#include <locale.h>
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>

int
main (void)
{
  locale_t loc = newlocale (LC_COLLATE_MASK | LC_CTYPE_MASK,
                            "en_US.UTF-8", 0);
  if (!loc)
    {
      perror ("newlocale");
      exit (1);
    }

  wchar_t *p1 = L"xyzzy", *p2 = L"XYZZY";
  errno = 0;
  int res = wcscoll_l (p1, p2, loc);
  if (errno)
    {
      perror ("wcscoll_l");
      exit (1);
    }
  char res_ch = res < 0 ? '<' : res > 0 ? '>' : '=';
  freelocale (loc);
  printf ("\"%ls\" %c \"%ls\" in locale en_US.UTF-8\n", p1, res_ch, p2);
}

$ gcc collation_test.c

$ ./a
"xyzzy" > "XYZZY" in locale en_US.UTF-8
