Error: Arithmetic overflow converting INTEGER(16) to INTEGER(4) at (1)
The error message is correct: You cannot fit the number into an INTEGER(4) as
this is bigger than "HUGE(0)".
As the overflow is intended, one can use -fno-range-check to disable this
checking and thus the error message.
I think one should do here the same as in primary.c and add the following to
the error message:
--- arith.c (revision 127237)
+++ arith.c (working copy)
