undefined reference to `cctz_extension::zone_info_source_factory'

I am having issues linking this on cygwin.

If I install the binary package (4.3), it won't load:

And then there's this:

I had a similar issue before, and it was solved by tweaking Makevars.
Hope there's an easy fix for this as well. Any ideas?
Seems like pasting with backticks messed up the formatting, but I'm posting anyways.

If you have a patch that is not affecting other builds I would be happy to consider. I don't know much about cygwin, so not sure I can be of any help.

Ran into the same problem with R on cygwin.

/usr/lib/gcc/x86_64-pc-cygwin/12/../../../../x86_64-pc-cygwin/bin/ld: ./libcctz.a(time_zone_info.o):time_zone_info:(.rdata$.refptr._ZN14cctz_extension24zone_info_source_factoryE[.refptr._ZN14cctz_extension24zone_info_source_factoryE]+0x0): undefined reference to cctz_extension::zone_info_source_factory' /usr/lib/gcc/x86_64-pc-cygwin/12/../../../../x86_64-pc-cygwin/bin/ld: ./libcctz.a(zone_info_source.o):zone_info_source.cc:(.debug_info+0xbc82): undefined reference to cctz_extension::zone_info_source_factory'
collect2: error: ld returned 1 exit status
make: *** [/usr/lib/R/share/make/shlib.mk:10: timechange.dll] Error 1

My business with timechange is as a dependency of lubridate. I tried older versions of lubridate, and the latest that builds is 1.7.9 (it featured cctz material, yet it builds). Starting with 1.7.9.2, this kind of error shows up. This is a good enough workaround for me for the time being.

Could it be that something in cygwin's /usr/share/zoneinfo is missing? I borrowed the directory from Gentoo, and that makes no difference.
