In one of the Windows system header files, an "interface" macro is
defined as:
#define interface struct
This results in some very strange build errors when also including the
descriptor-private.h header file. That's because the dc_usb_params_t
struct has a member field named "interface":
typedef struct dc_usb_params_t {
unsigned int interface;
unsigned char endpoint_in;
unsigned char endpoint_out;
} dc_usb_params_t;
As a workaround, define the WIN32_LEAN_AND_MEAN macro before including
the windows.h header file. This excludes some less common Windows API
declarations, including the above one.
