libtool versioning and sonames

[Andreas Metzler]

Hello,

gnutls recently had an incompatible API change (interfaces removed)
and therefore made this change: 

num     c       r       a
2.1.1   22      1       9
2.1.2   23      0       0

which is supposed to mean (according to the libtool manual), that
2.1.1 supported interfaces 13-22 and 2.1.2 supports only interface 23.
Which is perfectly all right and correct. However, the way libtool
tries to represent this information in sonames (on Linux) is rather
strange, it goes straight from libgnutls.so.13 to libgnutls.so.23. Is
this huge jump just bug or is there a reason for it?

thanks, cu andreas
