For cairo-1.6.4 CURRENT was 19, REVISION 5 and AGE 17, so libtool added

-set_version
19.17.5:2.0:3.0:4.0:5.0:6.0:7.0:8.0:9.0:10.0:11.0:12.0:13.0:14.0:15.0:16.0:17.0:18.0:19.0

to the link flags, thus ensuring that any application that used a previous
libcairo.so.2 would continue to be compatible with the current one.

Now, with libcairo-1.8.8, libtool again attempts to ensure that applications
that use a previous libcairo do not need to be rebuilt by adding all versions
from $CURRENT - $AGE to $CURRENT to the -set_version compatibility list.
Libtool does not know that there were no versions released between 19 and
10802.

I can only suggest that cairo add an exception for *-osf* to make the version
info 20:0:18 or something that will still give the same soname as cairo-1.6.4,
but not lead to problems with command line length.
