In #3872, the configuration of boost is switched from --without-xxx to --with-xxx.
Can you try it?
It should not build nowide. 🤞

#3894 adds the nowide option.
I can add it in #3872, but I don't want to steal @fpelliccioni 's pull request.

[gummif]

Ok thanks, lets hope these get merged soon.

I am facing some issues running the rebuild-dependencies.py script, so I think it is better that you steal it.

I managed to pin the revision to an older version by setting env var CONAN_REVISIONS_ENABLED=1 and using boost/1.74.0#3b52fbf45879b8b288e59d454d1c4765, if someone has the same issue.

@gummif There's any way to pin all index revision to not affect the actual state of build of conan for futures changes? This affected our Jenkins build and non-cached builds, we want to prevent it...
