 ## NOTES
 
-1. gcc 12.1 (May 2022) now detects and warns about an always-false condition in `fread` which caused a small efficiency saving never to be invoked. Thanks to CRAN for testing latest versions of compilers.
+1. gcc 12.1 (May 2022) now detects and warns about an always-false condition (`-Waddress`) in `fread` which caused a small efficiency saving never to be invoked. Thanks to CRAN for testing latest versions of compilers.
 
 2. `update.dev.pkg()` has been renamed `update_dev_pkg()` to get out of the way of the `stats::update` generic function, [#5421](https://github.com/Rdatatable/data.table/pull/5421). This is a utility function which upgrades the version of `data.table` to the latest commit in development which has passed all tests. As such we don't expect any backwards compatibility concerns. Its manual page was causing an intermittent hang/crash from `R CMD check` on Windows-only on CRAN which we hope will be worked around by changing its name.
 
+3. Internal C code now passes `-Wstrict-prototypes` to satisfy the warnings now displayed on CRAN.
