ummm, you're just wrong...

struct blah
{
	int whatever;
};

typedef struct blah	blub;
typedef struct *blah	blab;

blub *a[60];
blah b[60];

oh look... they're the same... huh... imagine the irony... one type...
and a pointer to a different type... *and they're the same thing*!!!
Don't hate me, I'm just in a bad mood.

PS onto the original question... I don't think they're the same... I'd
have to read the docs to be sure, but I think palette is an array of
rgb pixels or however they're defined... while bitmap is a 2d array of
pixels with bounds, etc included. and I do think that was on topic as
it was related to allegro... not some random library unrelated to
djgpp...
