| 3 | # Use Gnulib's robust chdir function. | |
| 4 | # It can handle arbitrarily long directory names, which means | |
| 5 | # that when it is given the name of an existing directory, it | |
| 6 | # never fails with ENAMETOOLONG. | |
| 7 | # Arrange to compile chdir-long.c only on systems that define PATH_MAX. | |
