/*

* 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.
