That's bizarre. It's pointing at this declaration:
struct
{
struct varlena hdr;
char data[TOAST_MAX_CHUNK_SIZE];
} chunk_data;
The only thing I can think of is that your compiler must be too stupid
to reduce the TOAST_MAX_CHUNK_SIZE expression to a compile-time
constant. I'd report that to Sun as a compiler bug --- this code has
been like this for a good long time, and no one has ever reported a
compiler unable to deal with it before.
A short-term workaround for you could be to compute TOAST_MAX_CHUNK_SIZE
by hand and change its #define in src/include/access/tuptoaster.h
to be a simple constant.
