--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed with the simple test case below where GCC could conceivably avoid
issuing the hint also because the function cannot be used as a replacement for
the call to time(). As declared, nice takes an argument but the call to time()
doesn't pass one, and returns void but the call is used in a context where an
int is expected.
$ cat b.c && gcc -S -Wall b.c
void nice (int);
int foo (void)
{
return time ();
}
b.c: In function ‘foo’:
b.c:5:10: warning: implicit declaration of function ‘time’; did you mean
‘nice’? [-Wimplicit-function-declaration]
return time ();
^~~~
nice
