/* COMPILATION NOTE:
Note that the Platform SDK headers and
link libraries for Windows XP SP2 or newer are required to compile
xmlrpc-c for this module. If you are not using this server, it is
safe to exclude the xmlrpc_server_w32httpsys.c file from the xmlrpc
project and these dependencies will not be required. You can get the
latest platform SDK at
http://www.microsoft.com/msdownload/platformsdk/sdkupdate/
Be sure after installation to choose the program to "register the PSDK
directories with Visual Studio" so the newer headers are found.
