Untested fix.  I believe this is because on mingw host HOST_LONG_LONG_FORMAT
is redefined to "I64", but that is a Microsoft-ism that pp_printf of course
doesn't handle.  pp_unsigned_wide_integer or pp_scalar it uses should handle
this fine by using the host sprintf into a temporary buffer and then just
appending the digit buffer.
As this needs mingw host, I can't really test whether it fixes this though, can
only bootstrap/regtest it on linux.
