     The current expression does not correctly handle the case of a
     text segment ending precisely at the end of a page; it causes the
     data segment to skip a page.  The above expression does not have
     this problem, but it will currently (2/95) cause BFD to allocate
     a single segment, combining both text and data, for this case.
     This will prevent the text segment from being shared among
     multiple executions of the program; I think that is more
     important than losing a page of the virtual address space (note
     that no actual memory is lost; the page which is skipped can not
     be referenced).  */
