mklink of pg_standby

Hi Simon, and Dave,Magnus.

About pg_standby, a link option cause a problem in windows(XP and 2k,2k3).
It is because the call of mklink is needed. Then, they are the new programs of 
VISTA and 2008. It is CreateSymbolicLink of API of kernel32.lib is equipped 
with mklink.

Therefore, I considered whether it should correspond by the 'Junction' or the 'Hard 
Link' this way and that. However, The addition thought that it was not desirable 
by the reason of the process of evolution functional pg_standby. A copy function 
is no problem. However, I think that it is necessary to write it to a document in 
order to avoid a user's confusion. probably, has that no source code corrects.

to Dave,and Magnus.
You can do more honest suggestion.:-)
