I remember when that came out...  I hadn't considered it because as I
recall, it was a fairly small subset - I though it was too small to be
useful for Unix porting.  Looking at v2.2 for x86, it doesn't support
floating point, short, long, unsigned, sizeof, casts, non-automatic
locals, arrays of pointers, structs or unions.  This makes it too
restrictive for porting Unix.
