 - Start from scratch (delete and re-extract the tcltls sources, make
   absolutely sure to use only one TCL version, re-configure tcltls).
 - Temporarily rename the /usr/local/include/openssl (probably add a
   00README.txt in /usr/local/include)
 - if the error persists, try to find out what the macro
   OPENSSL_API_LEVEL is set to:
    use this little hack from Stackoverflow:
      #define STR_HELPER(x) #x
     #define STR(x) STR_HELPER(x)
      #define AAA 123
     #pragma message "content of AAA: " STR(AAA)
   (just make a backup copy of openssl/macros.h and add that #pragma at
  strategic places)
 - or just #define OPENSSL_API_COMPAT to the default value (30000)
 Needless to say that on my system (opensuse 15.6, gcc 7.5.0), tcltls
2.0b1 configured and compiled with no problem against either tcl8.6 or
tcl9.0.2.

While looking at what I'd need to do to clear things down and start again from scratch, I spotted that I had downloaded openssl_1.1.1 myself in January 2023. Buoyed by this discovery, I did
make uninstall
from the openssl_1.1.1 download directory, then started again with tcltls 2.0b1, which... compiled and linked with no problem.
Many, many thanks to Ralf, Brian and Ashok.
