Leif,

Our build system defines .C as correct! I think it has been that way a very long time. 

https://github.com/tianocore/edk2/blob/master/BaseTools/Conf/build_rule.template#L109

[C-Code-File]
    <InputFile>
        ?.c
        ?.C
        ?.cc
        ?.CC
        ?.cpp
        ?.Cpp
        ?.CPP

Thanks,

Andrew Fish
