To my understanding this is legal C :

It's a K&R-style variadic functions, while their use is discouraged, they're
still legal C.
Variadic functions, in order to work in C, need at least one parameter so that
varargs can work.
int foo();
declares a function with an unspecified parameter list, not a variadic one. It
is specified by a definition somewhere:
int foo(a,b)
int a;
int b;
{ ... }
somewhere.
If Dstep encounters the first declaration form, your options are to:
1. reject it (a perfectly reasonable approach)
2. treat it as:
int foo(void);
I suggest option 2, which is what C++ does.
