[FFmpeg-user] Compilation Guide / MSVC on Wiki

[hinderanyoption81]

Hello,
Upon reading the "Compilation Guide / MSVC on Wiki", I am confused about at least three issues.
1. The Guide starts with a sentence "FFmpeg can be built on Windows with Visual Studio", and then it says:

Finally, run: For MSVC:
./configure --toolchain=msvc
make
make install

First, this is a Unix command that will not run on Windows. Second, does "make" refer to a Windows make.exe or a Unix make.exe, and where is that file located?

2. The Guide says that "www.mingw.org" is a prerequisite. Their web installer at osdn.net/projects/mingw/downloads/68260/mingw-get-setup.exe doesn't work (I get error messages like

http://prdownloads.sourceforge.net/mingw/msysCORE-1.0.19-1-msys-1.0.19-lic.tar.xz?download:cannot open URL; status = 12045

therefore I have to download their standalone installer. The "MinGW.org Compiler Collection (GCC)" at osdn.net/projects/mingw/releases/p15691 has 51 items; which ones should I download?

3. The Guide does not explain at what point in the procedure "C99-to-C89 Converter & Wrapper" has to be used and how to use it.

I wonder if Compilation Guide could be rewritten to provide more detailed information.
Any help is appreciated.
