From Bill Parker:

From Bill Parker:

	Add some additional memory-allocation failure checks in Lemon.

	Use NULL rather than 0 as the null-pointer constant in those
	checks.

From me:

	Catch one more of the NULL-vs-0 cases.

	Fix some failure messages to use fprintf(stderr, ...) -
	ErrorMsg() requires a file name and line number, and is
	generally used if you're going to continue rather than just give
	up.
