Keeping those #defines unconditional prevents new mingw builds from working, according to the commit description. So we have to either remove them entirely or do them correctly. Dropping this patch will keep the build from working. I suggest we keep this patch. A follow-up patch can us MS format specifiers or do any other adjustments that make this work better.
