Compatibility between g++ 4.1 and 4.2

[Stuart Brooks]

I was wondering if anyone could tell me whether C++ libraries compiled 
with gcc 4.2 are compatible with gcc 4.1 and vice versa. From 
http://gcc.gnu.org/onlinedocs/gcc/Compatibility.html I see that:
  "Starting with GCC 3.2, GCC binary conventions for C++ are based on a 
written, vendor-neutral C++ ABI "
and:
  "We have tried hard to provide a stable ABI that will be compatible 
with future GCC releases, but it is possible that we will encounter 
problems that make this difficult"

Does this mean I should have no problems?

Thanks
 Stuart
