    Hi,

    while memory debugging an app I found the following in fselector. This was
    checked in a minimal executable that just shows an fselector. Code is attached
    below. Tested against xforms lib version 0.88.1 and 0.89.2 using Solaris 2.5.1

    1. A leak return error is generated the only first time the fselector is called.

    Memory leaked by ignoring return value.

     Lost block : 0x000465e0 thru 0x00046a07 (1064 bytes)
                   block allocated at:
                             opendir()
                          tc_scandir()
                 scandir_get_entries()
                      fl_get_dirlist()
                        fill_entries()
                   fl_show_fselector()
                              browse()
      Stack trace where the error occurred:
                             realloc()
                          tc_scandir()
                 scandir_get_entries()
                      fl_get_dirlist()
                        fill_entries()
                   fl_show_fselector()
                              browse()
                     fl_object_qread()
                         fl_do_forms()
                                main()

    2. non-NULL second parameter in call to gettimeofday()

    The man page to gettimeofday() says:

         The second argument to gettimeofday() and settimeofday()
         should be a pointer to NULL.

    Just to make it clear. I haven't had any strange behaviour using the fselector.
    Just these memory debugging messages. Hope this is of some use...
