Thanks for the patches.

Could you please suggest a way to test for the ABI breakage ?

At any rate, I think that bumping the SOVERSION like this must be done 
upstream, don't you think?  I am not sure it is a good idea to have the 
Debian packaging messing with this.

I have also another question regarding the package naming.  I see that 
you introduced, in commit 95d5fc9 [1], the change in naming of 
libplplot-ada-dev to libplplotada1-dev.  Is there any specific reason you 
have chosen the number "1"?  Would it not be better to have both packages 
in sync, like libplplotadaN and libplplotadaN-dev?

Okay.

Best,
