comp.patents readers might find the following article of interest. Paul W Abrahams Software Patents: An Example of the Threat ACM SIGPLAN Notices 27, 8 (August 1992), 87-88 It briefly discusses US patent #4,992,971, issued 12 February 1991 to K. Hayashi of Tokyo and assigned to NEC. This patent covers the obvious technique for verifying at link time that a call to a separately compiled procedure matches the procedure's definition. (The method is to check that the number of arguments matches, and then to check that the attributes of each invocation argument matches the attributes of the corresponding procedure parameter.)
