:I've inherited some C code that had the following declaration in it:

:When I tried to compile this using Turbo C v2.0 and VAX C, it was flagged as
:a fatal error. My question is this: are zero length arrays allowed in the
:ANSI standard for C?

	No.  The intent of the original coder would most likely be
	satisified by

		char tbi[];  /* incomplete type; size to be filled in later */

	or

		char tbi[1]; /* maybe at the end of a structure template */
	.
