我有一个可以正常编译的应用程序，但是当我将 XCode 更新到 4.5 版时，它开始抱怨 libxml2。
问题出在这一行：
typedef void *(LIBXML_ATTR_ALLOC_SIZE(1) XMLCALL *xmlMallocFunc)(size_t size);
错误：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk/usr/include/libxml2/libxml/xmlmemory.h:66:39: Expected parameter declarator
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk/usr/include/libxml2/libxml/xmlmemory.h:66:39: Expected ')'

有人面临同样的问题吗？
问候！
