Broken Windows build

Hi all, Last week PHP_5_3 out of CVS built on my box under VC6; today it does not. I have been told on irc (thanks Liz) that there is no intention of fixing the breakage because 'the 2003 SDK has been a requirement since PHP 5.1'. This is the first I ever heard of any such requirement - everything has 'just worked' until now with standard out-of-the-box VC6, with or without SP* applied. Can someone please either explain the need to break a working build system just before a PHP release or else revert whatever changes caused the breakage? Thanks, - Steph
