GCC 14 makes implicit function declarations an error by default:
```
http.c: In function ‘get_HTTP_headers’:
http.c:21:32: error: implicit declaration of function ‘malloc’ [-Wimplicit-function-declaration]
   21 |         char *buffer = (char *)malloc(len + 1);
      |                                ^~~~~~
http.c:16:1: note: include ‘<stdlib.h>’ or provide a declaration of ‘malloc’
   15 | #include "utils.h"
  +++ |+#include <stdlib.h>
