bool is a keyword in C23

[mruprich]

GCC15 has landed in Fedora Rawhide and 'bool' is a new keyword in C23 standard. I have added a condition around the typedef for bool so that with newer GCC, the build won't fail with following error:

wildtest.c:35:14: error: ‘bool’ cannot be defined via ‘typedef’
   35 | typedef char bool;
      |              ^~~~
wildtest.c:35:14: note: ‘bool’ is a keyword with ‘-std=c23’ onwards
wildtest.c:35:1: warning: useless type name in empty declaration
   35 | typedef char bool;
      | ^~~~~~~

I see that all tests have passed here but I am also getting notifications from github about a failed MacOS test which I don't see listed here. The test runs roughly once per day judging from the notifications.

Can we merge this? I would like to just cherry-pick this into out package instead of handling patches. Thanks!

BTW, this contains a merge commit now... Anybody should press the rebase button.
