[bug #18961] configure enables both HANDLE_LLONG_MAX and HANDLE_LONG_LONG_MAX, resulting in a build error in GSFormat.m on FBSD 6.2

[Nikolaus Waxweiler]

Follow-up Comment #5, bug #18961 (project gnustep):

I found the error. GCC 4.3.0 brings its own limits.h which defines
LONG_LONG_MAX. Says cpp43 on my system when I paste the test code from
configure and add "LONG_LONG_MAX" and "LLONG_MAX":


#ifndef _GNU_SOURCE
        #define _GNU_SOURCE
        #endif
        #ifdef HAVE_STDINT_H
        #include <stdint.h>
        #endif
        #include <limits.h>
        #if defined(LONG_LONG_MAX)
        #if LONG_MAX == LONG_LONG_MAX
        #error long max equals long long max
        #endif
        #else
        #error long long max not defined
        #endif

LONG_LONG_MAX

LLONG_MAX

So they are both defined and both aliases for one and the same number. Now,
"./configure CC=gcc43 CPP=cpp43" tests things under gcc43 conditions but
doesn't actually set the compiler to gcc43 when gmaking, I have to explicitly
say "gmake CC=gcc43". Duh! I should have noticed this earlier.
