This information is from section D.1.3 (Page 340) of the "Microsoft
QuickC Programmer's Guide" and section E.3.3 (Page 269) of the
"Microsoft C Optimizing Compiler User's Guide" for Versions 5.00 and
5.10.

This message indicates potential problems but does not hinder
compilation and linking. The number in parentheses at the end of a
warning-message description gives the minimum warning level that must
be set for the message to appear.

The following is the warning:

C4028       parameter 'n' declaration different

            The type of the given parameter did not agree with the
            corresponding type in the argument-type list or with
            the corresponding formal parameter. (1)

Note: this message may appear when it should actually have produced
the warning C4074 if an ellipsis is used in the prototype.

The call of the function gave a parameter type that did not match up
with prototype and function definition, as in the following code
fragment:

void foo (int) ;

main ()
{
  float fp ;
  foo (fp) ;
}

void foo (int)
{
}
