This problem is present since v4.8 i believe (i tried also 4.8.1). Actually,
this happens because of this sequence in prefix.c:
--- cut ---
#include "config.h"
#include "system.h"
#include "coretypes.h"
#if defined(_WIN32) && defined(ENABLE_WIN32_REGISTRY)
#include <windows.h>
#endif
--- cut ---
In system.h we have this:
--- cut ---
/* Redefine abort to report an internal error w/o coredump, and
reporting the location of the error in the source file. */
extern void fancy_abort (const char *, int, const char *) ATTRIBUTE_NORETURN;
#define abort() fancy_abort (__FILE__, __LINE__, __FUNCTION__)
--- cut ---
And after that we attempt to #include <windows.h> in C++ mode, because we use
g++ in order to compile this .c file (why ?). In msxml.h "abort(void)" is a
member of IXMLDOMDocument interface:
--- cut ---
#if defined(__cplusplus) && !defined(CINTERFACE)
struct IXMLDOMDocument : public IXMLDOMNode {
public:
virtual HRESULT WINAPI get_doctype(IXMLDOMDocumentType **documentType) = 0;
virtual HRESULT WINAPI get_implementation(IXMLDOMImplementation **impl) =
0;
virtual HRESULT WINAPI get_documentElement(IXMLDOMElement **DOMElement) =
0;
virtual HRESULT WINAPI putref_documentElement(IXMLDOMElement *DOMElement) =
0;
virtual HRESULT WINAPI createElement(BSTR tagName,IXMLDOMElement **element)
= 0;
virtual HRESULT WINAPI createDocumentFragment(IXMLDOMDocumentFragment
**docFrag) = 0;
virtual HRESULT WINAPI createTextNode(BSTR data,IXMLDOMText **text) = 0;
virtual HRESULT WINAPI createComment(BSTR data,IXMLDOMComment **comment) =
0;
virtual HRESULT WINAPI createCDATASection(BSTR data,IXMLDOMCDATASection
**cdata) = 0;
virtual HRESULT WINAPI createProcessingInstruction(BSTR target,BSTR
data,IXMLDOMProcessingInstruction **pi) = 0;
virtual HRESULT WINAPI createAttribute(BSTR name,IXMLDOMAttribute
**attribute) = 0;
virtual HRESULT WINAPI createEntityReference(BSTR
name,IXMLDOMEntityReference **entityRef) = 0;
virtual HRESULT WINAPI getElementsByTagName(BSTR tagName,IXMLDOMNodeList
**resultList) = 0;
virtual HRESULT WINAPI createNode(VARIANT Type,BSTR name,BSTR
namespaceURI,IXMLDOMNode **node) = 0;
virtual HRESULT WINAPI nodeFromID(BSTR idString,IXMLDOMNode **node) = 0;
virtual HRESULT WINAPI load(VARIANT xmlSource,VARIANT_BOOL *isSuccessful) =
0;
virtual HRESULT WINAPI get_readyState(long *value) = 0;
virtual HRESULT WINAPI get_parseError(IXMLDOMParseError **errorObj) = 0;
virtual HRESULT WINAPI get_url(BSTR *urlString) = 0;
virtual HRESULT WINAPI get_async(VARIANT_BOOL *isAsync) = 0;
virtual HRESULT WINAPI put_async(VARIANT_BOOL isAsync) = 0;
virtual HRESULT WINAPI abort(void) = 0;
--- cut ---
This causes the conflict. A solution is to add a #define CINTERFACE to
prefix.c right before #include <windows.h>.
gcc v4.7 did not suffer from this problem because 'gcc' was used at this stage
instead of 'g++'.
