This seems to come from a CLT update: my Catalina box updated to 12.0 beta 5 overnight. And that has defaulted the SDK to 11.0. I wish they would not do that -- it is not the first time they have installed a beta CLT without asking and set the SDK for a future OS. I have tweaked configure for R-devel and R-patched so they install, but likely the better answer for me is to downgrade the CLT to 11.5 or set an SDK.

Re: [R-SIG-Mac] bzip2 configure error
Duncan, We have a bunch of bugs in configure (on all platforms) when used with -Werror which is default for some Apple compiler builds recently, the one below is just one for them (failing to include stdlib.h and string.h in the test). It may be worth filing a bug report, this should be a reasonably straight-forward task for someone to supply a patch to go through with -Werror and fix them.

Re: [R-SIG-Mac] bzip2 configure error
I seem to have got past this error by reinstalling Xcode. I'm not sure what went wrong with the old install; I'm pretty sure I did an R-devel build since installing Catalina.
