function! BuildAndRun()
    let qflist = getqflist()
    let run = '! ./%:t:r'

    if qflist == []
        exec run
    else
        for error in qflist
            if error["valid"]
                return
            else
                exec run
                return

Add this in vimrc and press <commar> + m to call make on the current buffer. If there were no valid errors, run the resulting binary. Doesn't scale well for big projects (e.g. binaries should not be in the same directory as src), but is quick and simple.
