| 8162 | 11 # The native Windows tmpfile function always tries to put the temporary |
| 12 # file in the root directory. (This behaviour is even documented in | |
| 13 # Microsoft's documentation!) This often fails for ordinary users who | |
| 14 # don't have the permissions to write in the root directory. | |
| 15 # | |
| 16 # We can't test for tmpfile even at runtime, since our test program | |
| 17 # might be running with privileges that allow it to write to the root | |
| 18 # directory, even though tmpfile wouldn't work in general. Instead, | |
| 19 # just test for a Windows platform (excluding Cygwin). | |
