|  *  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.
