Hello David,
I noticed a bit late (after sending my mail to the xml list) that you
also fighting
with the libxml on WIN32. Here some of my comments on the warnings.
Question , did you build the whole thing as a DLL or just static
compiled the tests?

wants a xmlReallocLoc (xmlRealloc is a macro) wants a void* a simple
cast removes this warning.

sockets in WIN32 are of type SOCKET wich is unsigned. I dunno if it will
be accepted in the main tree
to use SOCKET for sockets. and define SOCKET to be int on unix and
unsigned int on WIN32.

htons() wants a short and not an int a simple cast should remove the
warning , or patching the sources
to always use 16bit shorts for port numbers.

the prototype for getsockopt in WIN32 wants a char* so just a simple
cast should be ok.
if (getsockopt(s, SOL_SOCKET, SO_ERROR, (char*) &status, &len) < 0 ) {

casts should do no harm.

this should turnup on UNIX too ????

These all seem to need a cast before the return type.

Shouldn't there be constants defined for NAN and the like ?
