Looks like gcc doesn't define __OBJC__ when compiling an Objective-C file if 
it's using the c99 or gnu99 standard. Probably a compiler bug?

Summary:  Problem handling/formating long long numbers

Original Submission:  Jus try this:



NSNumber* testNumber=[NSNumber numberWithLongLong:3372036854775807LL];



NSDebugMLog(@"testNumber=%@",testNumber);

        ==> -2098855937              (Bad)

      

NSDebugMLog(@"[testNumber longLongValue]=%lld",[testNumber

longLongValue]);

        ==> -2098855937              (Bad)



fprintf(stdour,"[value longLongValue]=%lldn",[value longLongValue]);

        ==> 3372036854775807         (Good)

I investigated deeper and found that the problem seems to be not in GSFormat.

configure doesn't define HANDLE_LONG_LONG_MAX because LLONG_MAX is not defined.

LLONG_MAX is defined in limits.h if some compilation directives are defined. 
And in my case, it is not defined.

By using export CPPSFLAGS=gnu99 or CPPSFLAGS=c99, LLONG_MAX is defined so 
HANDLE_LONG_LONG_MAX is defined but now core/base no more compile (Protol 
definition conflict between NSObject.h and 
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.2.2/include/objc/objc.h)



Any idea ?

Problem seems to come from GSFormat wich seems to not handle double length 
modifier like hh, ll



There's also a documentation problem in NSNumber.m:

<term> long long</term>

<desc>%li</desc>

is the same as for long (it should be %lli instead of %li).



idem for unsigned long long
