[xml] Problem compiling libxml2-2.6.4

[Ian Marlier <ian onepost net>]

I'm trying to compile libxml2-2.6.4 on a Mac OS X machine.  Configure runs
fine, but make fails at the same place every time, and I don't know enough
coding to solve this...

I looked for the functions that were having problems, and this is what I
found:

[network:~/libxml2-2.6.4] marlier# grep -n "xmlFreeID" valid.c
2387: * xmlFreeID:
2393:xmlFreeID(xmlIDPtr id) {
2485:   xmlFreeID(ret);
2494: * xmlFreeIDTable:
2500:xmlFreeIDTable(xmlIDTablePtr table) {
2501:    xmlHashFree(table, (xmlHashDeallocator) xmlFreeID);
2592:    xmlHashUpdateEntry(table, ID, NULL, (xmlHashDeallocator)
xmlFreeID);
6301:          xmlFreeIDTable(doc->ids);
6498:          xmlFreeIDTable(doc->ids);
[network:~/libxml2-2.6.4] marlier# grep -n "xmlAddID" valid.c
2410: * xmlAddID:
2421:xmlAddID(xmlValidCtxtPtr ctxt, xmlDocPtr doc, const xmlChar *value,
2444:           "xmlAddID: Table creation failed!\n");
4117:        if (xmlAddID(ctxt, doc, value, attr) == NULL)
4314:        if (xmlAddID(ctxt, doc, value, (xmlAttrPtr) ns) == NULL)
[network:~/libxml2-2.6.4] marlier#





Any ideas?
