I have to admit that I know very little about handling libraries. 

Anyway, between 2.2.9 and 2.2.10, strcasecmp and strncasecmp was
removed. In 2.2.9 they don't show up in any header file, but do show up
on an objdump run (if I haven't misunderstood, this should give a list
of public symbols); 

        $ objdump -T libgmime-2.0.so.2.2.9 | grep .text
        [...]
        0000ea20 g    DF .text  000000ac  Base        strncasecmp
        [...]
        0000ead0 g    DF .text  00000093  Base        strcasecmp

Is this ABI breakage?
