I cannot seem to figure out how to read the lfn filenames. I used opendir()
and readdir(), but the seem to only return lower case versions of the file
names. In the following example, the file "ME" should be uppercase.  "ls"
seems to do this as well:

C:\datawh\Utilities>ls -la

drwxr-xr-x   4 dosuser  dos            96 Nov  3 15:26 ..
-rwxr-xr-x   1 dosuser  dos        101065 Jan 20 14:33 lcdir

Here's a sample program and the results:
C:\datawh\Utilities>gcc --version

C:\datawh\Utilities>gcc -o filename filename.c

C:\datawh\Utilities>filename
filename: .
filename: ..
filename: lcdir.c
filename: lcdir
filename: FileName.c
filename: lcdir.exe
filename: me
filename: filename
filename: filename.exe

C:\datawh\Utilities>type filename.c
#include <stdio.h>
#include <dirent.h>
#include <string.h>
int main(int argc, char **argv)
 {
 DIR *d = opendir(".");
 struct dirent *de;
 while (de = readdir(d))
  {
  printf("filename: %s\n", de->d_name);
  }
 closedir(d);
 return(1);
 }
