Fortunately, there is no need to search for older documentation,
as there is an up-to-date one:
http://ffmpeg.org/platform.html#toc-Microsoft-Visual-C_002b_002b-or-Intel-C_002b_002b-Compiler-for-Windows

The guide you linked uses strange / wrong configure options, so I cannot
really recommend it.

As said, the relevant question to fix the issue you reported is:
Does mingw support the I (capitel I) format specifier?
