These libraries are only needed by developers or those compiling PHP 5 under windows.
If you are neither, you have no need for these libraries as they are compiled into PHP 5 statically, so please don't waste my bandwidth.

Also note that libxslt is a modified build so that the static build links dynamically with libxml2.

Current library versions required for PHP:

Iconv 1.9.1 was used to compile these libraries so is included here

Iconv (Needed by all builds)
This is the standard iconv build from
ext/libxml DEF file
Most current DEF file in PHP CVS
The libxml2 and libxslt libs here were both built using VC++6
libxslt-1.1.22 is built WITHOUT crypo in exslt for compatibility reasons
Release Builds
Debug Builds
