- ``-Wunused-but-set-variable`` now also warns if the variable is only used
by unary operators.
+- The ``-Wimplicit-function-declaration`` warning diagnostic now defaults to
+ emitting an error (which can be downgraded to a warning with
+ ``-Wno-error=implicit-function-declaration`` or disabled entirely with
+ ``-Wno-implicit-function-declaration``) in C11 and
+ C17 mode. This is because the feature was removed in C99 and cannot be

- Implemented `WG14 N2775 Literal suffixes for bit-precise integers <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2775.pdf>`_.
- Implemented the `*_WIDTH` macros to complete support for
`WG14 N2412 Two's complement sign representation for C2x <https://www9.open-std.org/jtc1/sc22/wg14/www/docs/n2412.pdf>`_.
+- Removed support for implicit function declarations. This was a C89 feature
+ that was removed in C99, but cannot be supported in C2x because it requires
+ support for functions without prototypes, which no longer exist in C2x.
