Again, what exactly is 'R-patched'?  The latest daily tarball

https://stat.ethz.ch/R/daily/R-patched_2023-03-29.tar.bz2

just built for me with

checking for curl-config... /usr/local/bin/curl-config
checking libcurl version ... 8.0.1
checking for curl/curl.h... yes
checking if libcurl is >= 7.28.0... yes
checking if libcurl supports https... yes

and reports itself as

R version 4.2.3 Patched (2023-03-29 r84146) -- "Shortstop Beagle"

Although as I mentioned, I had not tested it against curl 8.0.1 and did 
not know if anyone else had.

See also https://bugs.r-project.org/show_bug.cgi?id=18497

The patch has been in R-4-2-branch since

r84053 2023-03-25 12:37:42 +0000 (Sat, 25 Mar 2023)

At this time of year one has to be very careful about 'R-patched' -- for 
example CRAN check results labelled 'r-patched' are at least mainly for 
4.3.0 alpha.
