Dodji, thank you for your suggestion. Unfortunately this doesn't work
for me, I've ran to the such issue:
$ abidw libtirpc.so > libtirpc.so.abi
$ abidiff libtirpc.so.abi libc-2.20.so
abidiff: /home/max/src/libabigail/src/abg-reader.cc:203: void
xmlNodePtr): Assertion `is_ok' failed.
Quick analysis showed, that abidiff deals with 'enum-decl' here, I'm
going to file a bug to bugzilla soon.
