I just recently discovered mingw-get / the Automated MinGW Installer. Great work! (I have used MSYS 1.0.11 for years and never touched it. Today I needed MSYS one a new computer.)
I noticed that when running the installer I couldn't deselect the C-compiler. That made me wonder if it shouldn't be possible to only install MSYS? That would be very useful for people that don't need any compilers. The reason I ask about this is that it would be nice to make the download as small as possible.
