gost.dll required but missing after latest Cygwin update

[Alan]

This seems related to openssl 1.1.1b1 but it affects multiple other
programs.

For example dig no longer works:

$ dig bytehouse.co.uk any

dig: dst_lib_init: crypto failure

I have been unable so far to find a workaround or fix. There's a libgost.so
in /usr/lib/engines-1.0 but no gost.dll anywhere:

I've attached a redacted cygcheck file.

Thanks for any advice,  Alan
