Subject: usbutils for Mac OS X and Cygwin

Hi Greg,

Now usbutils git almost builds successfully out of the box under Mac OS X
and Cygwin (using libusbx). Just wondering if you can accept the minor
fix for Mac OS X and suggest a way to fix cygwin build.

For Cygwin, there is a conflict with Cygwin's w32api package.

DATADIR conflicts with MinGW and cydwin's <objidl.h> in their w32api
package.
http://caca.zoy.org/changeset/3404

typedef enum tag DATADIR	{
        DATADIR_GET=1,
        DATADIR_SET
} DATADIR;

I do not know the proper fix, so I just temporarily change
objidl.h to

typedef enum tag DATADIR	{
        DATADIR_GET=1,
        DATADIR_SET
} DATADIR1;

After that I can build usbutils.

I only need one fix for Mac OS X as Apple's gcc compiler does not like
--as-needed.
