Version mismatch between code and libraries compiled with different gcc version

[Bud Davis <bdavis9659@xxxxxxxxxxxxx>]

hello,
 
i did RTFM on this, it was very informative but did not answer my question.
 
If I am using gcc-4.4, can i link to a library compiled with gcc-4.3 ?  
 
How about 4.1 ?
 
Or is compatability only when the exact 4.X compiler is used for both the libs and the other code.
 
 
thanks,
bud davis
