How can I set CURLOPT_CAINFO globally for PHP on Windows?

Question

I understand that I can set the option on any specific instance, however what I would really like is to set something up php.ini or somewhere similar which will handle this

Here is a patch to 'emulate' what we can see on linux when a valid crt data has been found at build time (which is the case for almost all distros):

http://www.php.net/~pierre/patches/curl_cacert_default.txt

it adds a (system) ini settings to define the path to the cacert, curl.cainfo=c:\curl\ca.crt

cacert data can be fetched here: http://curl.haxx.se/docs/caextract.html

DLL for php 5.3 can be found here: http://www.php.net/~pierre/test/curl-5.3-vc9-x86-ts-nts-cainfodefault.zip DLL for php 5.2 can be found here: http://www.php.net/~pierre/test/curl-5.2-cainfodefault.zip

Please let me know how it works.
