0009 dtc: Warning rather than error on possible truncation of cell values
0010
0011 We always evaluate integer values in cell arrays as 64-bit quantities, then
0012 truncate to the size of the array cells (32-bit by default). However to
0013 detect accidental truncation of meaningful values, we give an error if the
0014 truncated portion isn't either all 0 or all 1 bits. However, this can
0015 still give counterintuitive errors. For if the user is thinking in 2's
0016 complement 32-bit arithmetic (which would be quite natural), then they'd
0017 expect the expression (-0xffffffff-2) to evaluate to -1 (0xffffffff).
0018 However in 64-bit it evaluates to 0xfffffffeffffffff which does truncate
0019 to the expected value but trips this error message.
0020
0021 Because of this reduce the error to only a warnings, with a somewhat more
0022 helpful message.
