Ah, it's because Emacs uses C99 inttypes.h macros like PRIdPTR without also 
using the Gnulib inttypes module which implements these macros on platforms like 
MinGW where the macros don't work. This problem occurs elsewhere in Emacs in a 
couple of places, we just never noticed it. I installed the attached patch, 
which I hope fixes the glitch.
