I think the behaviour is somewhat expected, but undesireable. 
'1/name.o' gets added to the archive as 'name.o'.  'ar -rP main.a 
1/name.o' checks '1/name.o' against 'name.o', sees that they don't 
match, assumes it's a different object and adds it as 'name.o'.  Without 
the path information in the archive to check against this is just the 
nature of -P.  Is there anything that can actually be done about it?
