    tried looking at what `uname` returns?
    [wakko@ani:/] uname
    Linux
    [wakko@ani:/]

    [wakko@ani:/] locate stddef
    /usr/include/linux/stddef.h
    /usr/lib/gcc-lib/i486-linux/2.7.2.3/include/stddef.h
    /usr/lib/gcc-lib/i486-linuxchecker/2.7.2.3/include/stddef.h

    I don't believe you compile them like you do a program. SCIIW, but modules
    should be compiled with -c and not linked. Try ldd'ing one of them:

    [wakko@ani:/] ldd /lib/modules/2.2.10/block/floppy.o
    not a dynamic executable
    [wakko@ani:/]

    Sorry I can't help you on #3
