* The order of the following two lines is important. |

|
* FREAD_READS_DIRECTORIES is undefined before including git-compat-util.h |
|
* to avoid the redefinition of fopen within git-compat-util.h. This is |
|
* necessary since fopen is a macro on some platforms which may be set |
|
* based on compiler options. For example, on AIX fopen is set to fopen64 |
|
* when _LARGE_FILES is defined. The previous technique of merely undefining |
|
* fopen after including git-compat-util.h is inadequate in this case. |
