-Wconversion warns you every time a function call has the parameter passing altered by the presence of the function's prototype, which is to say that it will warn you every time you call any function (or method) which takes a char, unsigned char, short, unsigned short, or float. Not exactly useful.
At least until Xcode gets gcc 4.3, where -Wconversion has been renamed -Wtraditional-conversion, and -Wconversion gives useful warnings about variables that might have their value changed during the conversion.
This page http://developer.apple.com/documentation/Darwin/Conceptual/64bitPorting/building/building.html does seem to suggest that -Wconversion has its place but istm that you will have a lot of difficulty isolating the real problems from all of the error chaff.
