Another one, from https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82967#c1

#include <math.h>

void test (float pf, float inff)
{
  assert (pf == inff);
}


<source>: In function 'test':
<source>:5:3: warning: implicit declaration of function 'assert'; did you mean
'sqrt'? [-Wimplicit-function-declaration]
   assert (pf == inff);
   ^~~~~~
   sqrt

We should suggest including <assert.h> for this.
