I have now installed mingw on my local PC (RHEL-7)
gcc version 4.9.3 20150626 (Fedora MinGW 4.9.3-1.el7) (GCC) 

I see the format problem here as well and adding
-D__USE_MINGW_ANSI_STDIO does not help. Same as in Andrews's case.

So I wrote at test program that uses those offending formats, compiled
it with mingw 32 and 64 bit and run it on Windows 10. No problem.
Formats are interpreted correctly.

So it seems that "only" the warnings are wrong. I suggest to add -Wno-
format to the mingw configurations to silence the warnings (optimally
dependent on the mingw version but that is a bit hard to do -- and has
some overhead cost).
