Re: bool and C23

[Paul Eggert]

Thanks for catching that doc bug. I installed into Gnulib the stdbool 
patches with a fix for that, and also with one small change to 
tests/test-stdbool.c so that it depends on HAVE_C_BOOL instead of 
__STDC_VERSION__.

After we have more experience with this in Gnulib, we can start thinking 
about updating Autoconf.
