Array bounds checking with C????

[Frank [Who me?] Kuan]

	Why is it that most C compilers don't seem to support this
	nifty little feature?

	I'm working on a large project, and two of the worst debugging
	nightmares I've had were due to memory being overwritten from
	over indexing an array.

	I was thinking about writing some kind of preprocessor to
	check for this. Has anyone already written something like
	this?

	Thanks in Advance.
