More precisely, Dejagnu runs the tests through a main loop which is
copy/pasted all over the directories and ressembling something like:

  set dirlen [expr [string length "$srcdir/$subdir"] + 1];
  foreach file [lsort [find $srcdir/$subdir *.C]] {
      # If we're only testing specific files and this isn't one of them, skip it.
      set tfile [string range $file $dirlen end];
      if ![runtest_file_p $runtests $tfile] then {
	  continue
      }
      verbose "Testing $file"

      # We don't want old-dejagnu.exp to have to know about all the global
      # variables we use.  For now we tell it about CXXFLAGS and LIBS and
      # leave LDFLAGS alone.
      old-dejagnu $GXX_UNDER_TEST "$file" "$tfile" "" "$DEFAULT_CXXFLAGS" "-lstdc+
  }


Note the "lsort" command.
