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
