#1365: bitwise-not returns wrong values on non-negative arguments
----------------------------+--------------------------------
Reporter: johnwcowan | Owner:
Type: defect | Status: new
Priority: minor | Milestone: someday
Component: core libraries | Version: 4.12.0
Keywords: | Estimated difficulty: trivial
----------------------------+--------------------------------
The expression {{{(bitwise-not 0)}}} returns 4611686018427387903 (i.e.
0x3fffffffffffffff) instead of -1. The {{{fxnot}}} procedure does not
have this problem, nor does the numbers-egg version of {{{bitwise-not}}}.
However, {{{(bitwise-not -1)}}} correctly returns 0.
