It seems to be pretty stable and handles the whole language (except possibly enum's, which we haven't tried). The major problem is that ints are 16 bits long. This causes difficulties in moving code from machines where ints and pointers are the same size. Actually, it causes problems only when the author of the code was careless about typing, but that seems to be the norm. The code generated is better than the average pcc derivative. I haven't had a copy of Whitesmith C for the 68K so I don't know about that. My experience with Whitesmith on a Z80 is that the library contains gratuitous changes from the normal Unix version, prehaps to prove that it was independently developed.
