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

|
*
|
||
|
* SUPPRESS_FOPEN_REDEFINITION is defined 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.
