cdecl error: expected initializer before

Question

I have a problem with the cdecl calling convention:

void Test1(char* str, ...)           // ok
{}

void cdecl Test2(char* str, ...)     // error: expected initializer before 'Test2'
{}

int main()
{}

What should I do to make the compiler recognize the cdecl calling convention?

Thanks!

Platform: Windows 7; MinGW; GCC 4.6.1

I cannot modify those functions, since they are part of "Microsoft Excel Developer's Kit, Version 14", in the file FRAMEWRK.H:

void far cdecl debugPrintf(LPSTR lpFormat, ...);
LPSTR GetTempMemory(size_t cBytes);
void FreeAllTempMemory(void);

Prepend it with two underscores, like this: __cdecl
