+ * @param     pachFilename  Pointer to modulename. Not zero terminated!
+ * @param     cchFilename   Modulename length.
+ * @param     plv           Loader local variables? (Struct from KERNEL.SDF)
+ * @param     pful          Pointer to flags which are passed on to ldrOpen.
+ * @param     lLibPath      New parameter in build 14053.
+ *                          ldrGetMte calls with 1
+ *                          ldrOpenNewExe calls with 3
+ *                          This is compared to the initial libpath index.
+ *                              The libpath index is:
+ *                                  BEGINLIBPATH    1
+ *                                  LIBPATH         2
+ *                                  ENDLIBPATH      3
+ *                              The initial libpath index is either 1 or 2.
+ *
+ * @sketch
+ * This is roughly what the original ldrOpenPath does:
+ *      Save pTCBCur->TCBFailErr.
+ *      if !CLASS_GLOBAL or miniifs then
+ *          ldrOpen(pachFilename)
+ *      else
+ *          if beglibpath != NULL then path = 1 else path = 2
+ *          if (lLibPath < path)
+ *              return ERROR_FILE_NOT_FOUND; (2)
+ *          Allocate buffer.
+ *          loop until no more libpath elements
+ *              get next libpath element and add it to the modname.
+ *              try open the modname
+ *              if successfull then break the loop.
+ *          endloop
+ *          Free buffer.
+ *      endif
+ *      Restore pTCBCur->TCBFailErr.
