 1.6  28-Sep-2024  rillig lint: reword warning about cast between unrelated pointer types

The phrase "may be troublesome" was too unspecific to be useful.
 1.5  07-Aug-2023  rillig branches: 1.5.2;
tests/lint: show that portable mode depends on PTRDIFF_TSPEC

Since 2023.07.08.12.45.43, lint warns in lib/libkvm on i386.
 1.4  08-Jul-2023  rillig lint: warn about pointer casts between different kinds of types

Pointer casts from an integer type to a floating-point type and vice
versa get a 'maybe troublesome' warning now. The previous assumption
that all types of the same bit-size are convertible may have been valid
from a technical point of view, but still such code should get more
attention.

The rules for struct and union types could be made more fine-grained
later, if the need arises. To suppress this warning, it's always
possible to cast to an intermediate 'void *'.
 1.3  08-Jul-2023  rillig lint: do not use portable type sizes in integer constraints

This reverts the change from tree.c 1.547 from 2023-07-03. Back then, I
didn't know that the actual value from a type's 'portable size in bits'
was not supposed to be used.
 1.2  05-Jul-2023  rillig tests/lint: spell platform identifiers for 'long double' consistently

The test file names don't have a hyphen, so the identifiers shouldn't
have one either.
 1.1  05-Jul-2023  rillig tests/lint: add platform-specific tests for troublesome pointer casts
 1.5.2.1  02-Aug-2025  perseant Sync with HEAD
