It is an entirely new program that has been designed to provide fortran 95 support and extensibility for future fortran language standards, as well as providing backwards compatibility for fortran 77 and nearly all of the gnu language extensions supported by g77. A variadic function is support by the compiler that allows a programmer to write a function which accepts a variable number of arguments. Even if it might look the same to a programmer, max in fortran is not required to be a function, variadic or otherwise it can be implemented as a capability built into the compiler to recognise a sequence of tokens and expressions, and emit as much code. The generic forms min and max were not a manditory part of the fortran 77. Start up mingw, and navigate it to the directory containing the module whee.
