Some of the PECL extensions compiled without really complaining with the
new experimental branch (on Windows). Anatol's own xmldiff,
php_blenc.dll (but it did not work), php_uploadprogress.dll and
php_timezonedb.dll.
The BC break should probably be even greater, so that cases like the
blenc extension do not occur.
I have converted one of my own extensions (that is not even on PECL):
php_ffmpeg.dll. I did not do that (yet) with ifndef's, but just with
global searching and replacing. So I have two sources for the same
extension right now.
