My mistake, I was looking at the ouput of my "char x;" example,
which IMHO is even worse.
covell@xxxxxxx ~>cat foo.c
#include <stdio.h>
int main()
{
char x;
if ( x )
{
printf ("\n We got here\n");
}
else
{
// We never get here
printf ("\n We never got here\n");
}
exit (0);
}
covell@xxxxxx ~>gcc -Wall foo.c
foo.c: In function `main':
foo.c:17: warning: implicit declaration of function `exit'
