The following little file

	#include <netinet/in.h>

	uint16_t f(uint16_t in) {
		return htons(in);
	}

, when compiled with -Wconversion:

	cc -Wconversion -c t.c

, gives the following mistery warning:

	t.c: In function `f':
	t.c:4: warning: passing arg 1 of `__bswap16' with different width due to prototype

The compiler is:
	Using built-in specs.
	Configured with: FreeBSD/i386 system compiler
	Thread model: posix
	gcc version 3.2.1 [FreeBSD] 20021119 (release)

Any clues? Thanks!
