I was having some problems getting some code to properly compile. I have
isolated the problem to some code involving '#elif' preprocessor
statements.
 
The following sample code illustrates the problem:
 
=========================================================
#include <stdio.h>

#define TEST2 1

main()
{
int i,j,k;
 
i=j=k=1;
 
#ifdef TEST1
i=2;
#elif TEST2
j=2;
#else
k=2;
#endif

printf("%d %d %d\n", i, j, k);
} 
====================================================

Now, I feel that the output should read: 1 2 1
 
However, SAS/C produces: 1 1 2
 
My UNIX system at work produces the correct answer (1 2 1).
 
Is this a known SAS/C bug?
 
I am running 5.10a
