Arithmetic Operations on Signed Short Values
--------------------------------------------

In C 5.10 and Microsoft QuickC(R) 2.00, arithmetic on constants of
type signed short is done using a signed long value. C 6.00 conforms
to the ANSI specification by performing arithmetic operations on
signed shorts and yielding a signed short value.

This causes overflow in some instances of constant arithmetic, most
noticeably, multiplication. For example, when interpreted as a signed
short, 48*1000 results in a value of -15232 rather than 48000.
