Hi,
I am trying to use CamlIdl (Ocaml 3.07+2 win32) and have this case in which 
I understand what is happening, not sure why it  has been implemented thus. 

For the following structure, when SOME_VAR is *not* defined, 
---
struct my_test {
	int x;
#ifdef SOME_VAR
	int y;
#endif
};
---

CamlIdl converts this to 
---
let my_test = int
---

This is because a structure with one element is getting special attention in 
Struct.ml_declaration. 

Knowing very little about the MIDL specification, I attempted to run this 
against a MIDL compiler for the following result -
---
struct  my_test
    {
    int x;
    };
---

It seems that the special casing of the single element is not the best of
things for my application, since any reference to the element x will have to be
modified in the Ocaml program depending on whether SOME_VAR is defined or not. 

IMHO this seems like a bug. Was wondering if there is some other explanation 
for this.

Thanks in advance for any help.
