size_t, which is the type returned by sizeof(), is defined in Standard C
to be an "unsigned integral type". In particular its actual size is not
specified. On Palm OS it is probably long, which is different from Int.

Believe it or not, you are having a similar problem to the "StrPrintF
Bug?" thread. Without a prototype, the compiler has no opportunity to
convert the arguments you give to the types expected by the parameters
of the function you're calling. The onus is then on you to get it right.
When you pass long to something expecting int, you're not getting it right.
Life really is easier when you ensure that there's a prototype in a header
file for every extern function you call. There's a reason why prototypes
were added to the language... :-)
