  34  * has been compiled. If you get a compiler warning when calling
  35  * g_stat(), do take it seriously and make sure that the type of
  36  * struct stat the code in GLib fills in matches the struct the type
  37  * of struct stat you pass to g_stat(). To avoid hassle, to get file
  38  * attributes just use the GIO API instead which doesn't use struct
  39  * stat.
  40  *
  41  * Sure, it would be nicer to use a struct with 64-bit st_size and
  42  * 64-bit st_*time fields, but changing that now would break ABI. And
  43  * in MinGW, a plain "struct stat" is the one with 32-bit st_size and
  44  * st_*time fields.
