Correct me if I am wrong, but using Pd-extended vs Pd-vanilla of the  
same version is no more incompatible than using Pd-vanilla 0.40 vs.  
0.39.  If you use [declare] in a patch in pd-vanilla 0.40, then it  
won't work in pd-vanilla 0.39.  If you use [atan2] in Pd-vanilla 0.37  
then it won't be compatible with pd-vanilla 0.38, and vice-versa.

Pd-extended 0.39 is basically like half way between pd-vanilla 0.39  
and 0.40 since it includes patches that get included in 0.40, but  
doesn't include miller's 0.40 changes.

This is the reason why I made the [hcs/version] object, you can issue  
a warning if someone is using your patch with a version not tested or  
known to be incompatible.  It's not in Pd-vanilla, I never submitted  
it to the patch tracker since I wasn't sure of the best interface for  
it, like maybe it should be a message like [;pd version(, then you  
listen on [receive pd]-[route version] for the response.
