Yes. It breaks ABI for the very specific case which is mentioned in
the commit message, the RELEASE-NOTES document for next release and
the message I've posted to this list warning of such fact.

And it breaks it in the mentioned case relative to libcurl 7.19.4 and
7.19.3 for the simple reason that the patch you previously provided,
included for 7.19.3, did not adhere to the requirements which are
enforced and used by libcurl since version 7.19.0 _AND_ none of us had
noticed this previously.

For additional potential ABI break done in libcurl 7.19.0 relative to
previous versions you can find more details in lib/README.curl_off_t
included with all 7.19.X releases as well as in the 7.19.0 release
notes. It seems that you missed or didn't notice its existence.
