The following problem can cause bootstrap comparison failures in some
circumstances (and was originally observed when bootstrapping with CFLAGS=-g
BOOT_CFLAGS=-g).

Unit numbers are passed and stored internally as GFC_INTEGER_4, but we don't
error out on too large numbers (like the one that don't fit inside a
GFC_INTEGER_4).
