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). */
