>Description:
The functions getline() and getdelim() in /usr/include/stdio.h are defined
for ANSI C source code, which is wrong.  They should be defined for
POSIX.1-2008 code instead.
>How-To-Repeat:
Try to compile

    #include <stdio.h>
    void getline(void) { }
    int main(char** argv, int argc) {
        getline();
    }

with command
    gcc -ansi -o example example.c
>Fix:
Move the definitions into proper section of the header.
