Hmmm, I am using gcc 3.3 (debian sid).

So does mine.

Well, does symbol.h have a `ctype' member in your copy? It doesn't in
mine. And line 44 of parse.c says:
sym->ctype.base_type = ctype->base_type;
which fails because sym is a struct symbol * and struct symbol doesn't
have a ctype member. And FWIW the compilation fails with gcc-3.2 too.
I have included the version of symbol.h that I have below. Could you
compare that against yours and/or do a pull and see if it still works
for you?
