If I compile the following code segment with MPW-C 3.0 using 'c -c file.c' 
no errors are reported.  However, when I compile it with LSC 3.0 it 
reports an error because the array is unindexed.  If I put in 6 as the 
index then LSC reports an error for trying to initialize an automatic 
array.

According to K&R (1st edition) automatic arrays cannot be initialized.  
What does K&R's 2nd edition and the ANSI standard say about this?

Is this a bug in the MPW C compiler? Or is Apple following the ANSI 
standard on this, while THINK Technologies follows K&R?

I couldn't find anything in the MPW-C manual about initializing automatic
arrays.

One last thing before I show you the code fragment:  MPW-C leaves a .o 
file, of length 0K, in the directory when I compile with the -c option (no
code generation option).  Is this a bug, feature, oversight, or what?

#ifdef THINK_C
#define  real  double
#else
#define  real  extended
#endif

real XFactorial( x )
   real x ;
{
   real  coef[] = (  76.18009173, -86.50532033, 24.01409822
                     -1.231739516, 0.120858003e-2, 0.536382e-5 ) ;
         :

}
