I used the gui installer and no matter what I select, the C:\MinGW\bin\ folder only contains 2 files: mingw-get.exe and pkginfo.exe. If I run the command to install gcc or anything, it tells me that it's already installed. I checked through the documentation and everywhere I look it seems that this should not be how it works, but for some reason it's that way for me.
