Prototypes and ID lists

[John F. Haugh II]

Greetings.

I have a question about function declarations.

Suppose I prototype a function with

extern struct passwd *getpwuid (uid_t uid);

and later in the same compilation unit have a declaration

struct passwd *
getpwuid (uid)
uid_t uid;
{
	[ stuff ]
}

Is my [ supposedly ] ANSI-compliant compiler free to warn
me that getpwuid() has been redefined?  Is this just a
warning or should this be a fatal error?  And the final
trick question - was this ever illegal?

The relevant section is [ I think, dyslexia not withstanding ]
3.7.1.  It is unclear, except for stating that you may use
an identifier list or a type and identifier list.

Relevant draft information - this is the January 1989 draft.
