   4 Subject: Bump HAL_PATH_MAX to 4096
   5
   6 Some bits in the code use realpath() with destination paths of size
   7 HAL_PATH_MAX. This potentially breaks on systems where PATH_MAX is bigger than
   8 HAL_PATH_MAX (which was 512 until now).
   9
  10 Since we can't use PATH_MAX directly (due to platforms like GNU/Hurd, which
  11 apparently don't have it), just bump HAL_PATH_MAX to 4096 (as PATH_MAX is on
  12 Linux), to avoid potential buffer overflows and also fix hal on Linux when
  13 enabling FORTIFY in gcc.
