Problem with volatile?

Running 2.95.3 under cygwin I get a problem with the following code:
struct SID
{
int i;
int j;
};
static volatile SID *fred;
void test(SID *bill)
{
*fred=*bill;
}
The compiler outputs the following message:
bash.exe-2.05$ g++ f.c -c -of.o
f.c: In function `void test(SID *)':
f.c:13: passing `volatile SID' as `this' argument of `struct SID &
SID::operator =(const SID &)' discards qualifiers
If I replace the struct SIF by int:
static volatile int *fred;
void test(int *bill)
{
*fred=*bill;
}
it compiles clean
I want the pointer fred to point to a volatile area which I can then read
and write.
Any ideas what I am doing wrong?
Thanks in advance
Kevin
