Thanks a lot. This is very helpful.

There are two problems.
1. I need do understand better if an update of the library (change in the symbols table)
requires a bump in the abi version or not.
You seem to have solved that problem.
2. I need to make PyQt-Qwt compile and work with the qwt library.
The best solution is to fix the PyQt-Qwt code (SIP) but I haven't found out how to do that
but by patching qwt, it works perfectly.
Now I am updating Qwt to version 6.1.3 and if I want to add the patch, the time is right to do it
but I want to be sure that the patch doesn't make problems for other users of the library.
I hope this explains my problem :)
