Pointer to function conversions (11.1)

[pkruk]

Hello,

rule 11.1 disallows conversions between function pointers and any other type than integral type.

1. conversion between compatible function types - are they allowed? For example:

Code:

typedef struct S1 { int x; } TS1;
struct S1 (*f1)();
TS1 (*f2)();
f1 = f2; // Is this compliant?

2. what about following case?

Code:

enum STYPE_LIST {
        TYPEA,
    };

    typedef int (*func_t)(char *);
    typedef STYPE_LIST (*func_t2)(char *);

    void moo() {
        func_t p;
        func_t2 p2;
        p= (func_t)p2;  // Is this compliant? Enum vs int
    }
