The warning (I get rather a lot of them) is caused by the
compat/fopen.c included when FREAD_READS_DIRECTORIES is defined. I
tried moving the #undef fopen to git-compat-util.h but that resulted
in a broken build and me reaching the end of my limited ability with
c.

In file included from cache.h:4,
                 from daemon.c:1:
git-compat-util.h:209:1: warning: "fopen" redefined
In file included from git-compat-util.h:51,
                 from cache.h:4,
                 from daemon.c:1:
/opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.3.0.0/3.3.2/include/stdio.h:110:1:
warning: this is the location of the previous definition

The warnings are harmless, though untidy.

I don't believe it's anything to do with _LARGE_FILES. Could you try
building first with one commented out, then the other? I don't think I
have access to a 4.3.3 box any more.
