Hey David,
Here's a link from Apple's site:
http://developer.apple.com/library/mac/#documentation/Carbon/Conceptual/Carbon64BitGuide/PortingTo64Bit/PortingTo64Bit.html#//apple_ref/doc/uid/TP40004381-CH3-SW7
While this reference is related to 64-bit programming with Carbon, it
also addresses (under section "Common Pitfalls") mistakes developers
often make while writing code that would render it unusable if
built/run on 64-bit platforms.
The same doc also should help you get started porting if you decide to
go that route.
