Bug ID: 227329
Summary: [PATCH] bin/expr: do not fail with "overflow" if no
overflow occurs
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin

Patch to fix the issue
It is possible to trigger an overflow error message with expr, even though no
overflow would occur:
$ expr -- -36854775800 - \( -9223372036854775807 - 1 \)
expr: overflow
$ _
The function assert_minus() verifies subtraction in an invert addition case,
which is not correct.
