Sorry for the omission - I assumed that most people would recognize 
the above as ANSI standard C.
I am using Turbo C version 1.0 on an IBM XT under PC DOS 3.3. 
Turbo C supports both ANSI and K&R.

My other mistake was assuming that most people would recognize the
advantage of the above prototype over K&R C - It lets the compiler
do type checking and coerce the arguments of a function call to
proper type if necessary. Unfortunately, the most desirable 
style is not always the most portable.

A program to convert from ANSI C to K&R has not yet been brought
to my attention ...

The moral for C (as for every other programming language)
is to code in a manner to be as portable as possible across machines,
compilers, and dialects of the language, and thus obviate the need
for non-standard preprocessors in the conversion process.
