Bonjour

Here is a crude workaround.

-------------
#include <stdlib.h>
char * realpath (const char *, char *);

--------------------------------
#include <stdlib.h>
#include <limits.h>
#include <sys/stat.h>
#include <errno.h>

char * realpath (const char * file_name, char * resolved_name)
{
  struct stat stbuf;

  if (file_name == NULL || resolved_name == NULL)
  {
     errno = EINVAL;
     return 0;
  }

  if (*file_name == '\0')
  {
     errno = ENOENT;
     return 0;
  }

  if (stat(file_name, &stbuf) != 0)
     return 0;

  _fixpath (file_name, resolved_name);
  return resolved_name;
}
--------------------------------

The big difference with _fixpath is that it actually check for 
the path existence.
