Here is the output of `grep -R PATH_MAX suckless-tools-38/*`:

    dmenu/dmenu_path.c: char buf[PATH_MAX];

Comments
--------

Here are comments on the patch...

     void
     scan(void) {
    -   char buf[PATH_MAX];
    +   char *buf = NULL;
    +   char *new_buf = NULL;
    +   size_t buf_size = 0;

In this function we turn `buf` into dynamically allocated string.


            while((ent = readdir(dp))) {
    +           buf_size = strlen(dir)+strlen(ent->d_name)+2;
    +           if(!buf || strlen(buf) < buf_size) {
    +               new_buf = realloc(buf, buf_size);
    +               if(!new_buf)
    +                   die("realloc failed");
    +               buf = new_buf;
    +           }

For each directory entry we create or adapt the buffer size.


            }
    +       free(buf);

We free the buf when done.
