i've just fixed your enum bug, but then i read k&r2, p213:
``...incomplete enumeration types do not exist; the tag of
an enum-specifier without an enumerator list must refer to
an in-scope specifier with a list.''

i'll double-check the standard, but i think lcc had
it right, and gcc has it wrong.
if so, i'm undoing my `fix'.

here's a simple example of the error.

% cat bug1.c
typedef enum foo Foo;
enum foo { one, two, three };
Foo x;
