2184. Missing C compatibility entry for decrement of bool

Section: C.6.4  [diff.expr]     Status: CD4     Submitter: CWG     Date: 2015-10-21

C permits decrementing a _Bool operand, but C++ has never allowed that operation on bool operands. Since there is some code that maps those types together for cross-language compatibility, it might be worth mentioning the different behavior (and, with the adoption of P0002R1, for increment as well).

Notes from the June, 2016 meeting:

This issue will be handled editorially and is placed in "review" status until that point.
