Oops, 
It looks like I cannot paste correctly, 
like 3 should read like this :
char _unused2[15 * sizeof (int) - 2 * sizeof (void *)];

note that the "-" missing, thanks to leppie for pointing this out.

Summary:  pnet c loses the constantness of integers in array calculation

Original Submission:  test.c 
line 1:int x=15 * sizeof (int) - 2 * sizeof (void *);
line 2:const int x2=15 * sizeof (int) - 2 * sizeof (void *);
line 3:char _unused2[2 * sizeof (void *)2 * sizeof (void *)];

test.c:3: error: constant value required

I have traced this to 
ILNode_CSemAnalysis(ILNode_ToConst)
and replace the error with a warning as a workaround 
==      CCErrorOnLine(yygetfilename(node), yygetlinenum(node),
++     CCWarningOnLine(yygetfilename(node), yygetlinenum(node),
