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