c2hs doesn't understand enums on Mac OSX

Mac OSX libraries are full of the following:

enum {
kClippingCreator = 'drag',
kClippingPictureType = 'clpp',
kClippingTextType = 'clpt',
kClippingSoundType = 'clps',
kClippingUnknownType = 'clpu'
};

c2hs has problems dealing with 'characters' in enum definition.

This problem prevents ApplicationServices from being parsed and this constitutes for the most of Mac OSX API

Not obvious what to do about this. The C99 standard says:

The value of an integer character constant containing more than one character (e.g.,
'ab'), or containing a character or escape sequence that does not map to a single-byte
execution character, is implementation-defined.

and language-c raises a corresponding error if you try to do anything that accesses the integer value of a multi-character constant.

FYI, these are FourCCs, or four-character codes, that is, ASCII strings packed into 32-bit big-endian integers.
