mupdf - erroneous macro

Question

I'm trying to compile mupdf on Windows 7 using mingw gcc. It is taking exception with the following line in context.h

#define fz_throw(CTX, ERRCODE, MSG, ...) fz_throw_imp(CTX, __FILE__, __LINE__, ERRCODE, MSG, __VA_ARGS__)

With the error:

\mupdf\include/mupdf/fitz/context.h:70:105: error: expected expression before ')' token

Supposedly this code compiles with gcc. What is the particular issue here?
