Another example, to explicit show this kind of bug:
[EMAIL PROTECTED]:~/programming/c/problem$ cat problem.c
#include <stdio.h>
#include <stdlib.h>
#include <wchar.h>
int main (int argc, char ** argv) {
wprintf ("Hello,\n"); // L is missing.
return EXIT_SUCCESS;
}
[EMAIL PROTECTED]:~/programming/c/problem$ gcc -Wall problem.c -o problem
problem.c: In function 'main':
problem.c:7: warning: implicit declaration of function 'wprintf'
[EMAIL PROTECTED]:~/programming/c/problem$ ./problem
[EMAIL PROTECTED]:~/programming/c/problem$ gcc -v
