I've found several bugs--I can't remember them all now, but I posted them
on the Manx BBS, with code fragments that demonstrate the bugs.  I am
pretty sure they're bugs and not my mistakes.

For example, main(){printf("%s","A\x20" "B");} does not print "A B",
as expected.  It prints a single space.  The string concat doesn't work
properly with the escape character, I guess.

Also, enum's (or typedef enum's) in structure definitions can cause problems.
If you initialize a structure with enums in it, and then try to read the
initialized values, you get garbage.  Also, I think there were problems
with passing enums as arguments to functions.

I also got a few internal errors with the X->Y++ and X->Y += Z constructs.
The code fragments, anyway, are on the Manx BBS, 201-542-2793.
