The following code fragment gives a "Suspicious pointer conversion"
warning message when compiled by Turbo C++ 1.0 (in C mode).  It seems
that the structure member's type information is getting lost.  An
explicit cast (enum day_t *) gets rid of the warning message.  However,
am I being dense or has someone else seen this problem?

enum day_t {mon, tue, wed, thu};

struct date_t
{
    enum day_t day;
};

void foo(enum day_t *dtp)
{
    *dtp = tue;
}

void main(void)
{
    struct date_t bar;

    foo(&(bar.day));	/* <--- Suspicious pointer conversion */
}
