Subject: [PATCH] windows: use c_void from winapi (#235)

The `SelectObject()` call accepts a `HGDIOBJ` which is typecast to a
`std::os::raw::c_void` when building using libstd, and is its own thing
when building with std disabled:

winapi/0.3.9/src/winapi/lib.rs.html:
    #[cfg(feature = "std")]
    pub use std::os::raw::c_void;
    #[cfg(not(feature = "std"))]
    pub enum c_void {}

This patch uses `HGDIOBJ` as the typecast as necessary.
