Rule 11.1, 11.2 (and others?) vs conversion caused by equality operators (and similar)?

[pkruk]

Hello,

rules 11.1 and 11.2 disallow conversions between pointer to a function or incomplete type, and any other type:

Code:

void (*fp1)(short);
void (*fp2)(int);

fp2 = fp1;          /* Not-compliant - different function */
fp2 = 0x8000;       /* Not-compliant - integer */

What if the conversion happens for example in equality operator:

Code:

fp2 == fp1;         /* Compliant or Not-compliant ? */
fp2 != 0x8000;      /* Compliant or Not-compliant ? */

Following example from Rule 11.1 suggests it's also non-compliant:

Code:

if ( fp2 != NULL )  /* Compliant - exception 1 (NULL) */
