Right. I have a patch that I asked some of the people who distribute 
windows builds of libxml2 to take a look at so that the lib gets built 
by default.

It should be as i just checked it. It contains the builds I have been 
maintaining for the past few years now and the ones Edin uses for the 
windows builds. The libxslt build there has been required from day one 
cause it a customized build. It's just recent that the libxml2 build is 
now non-standard as well.
At that URL you should find both release and debug builds of libxml2 and 
libxslt specifically for building with PHP.

Older versions will still build with the standard libxml2 builds, just 
not the ones I provide. They will compile, but the thread cleanup 
handling will be a bit pooched. Best I could do if this is absolutely 
necessary is to build and provide all 3 libs and change the code on the 
recent branches (we've change 6, 5.2 and domxml in 4.4) to use 
libxml2_a_dll.lib (my proposed name for the new library).
