https://core.tcl-lang.org/tcl/wiki?name=Migrating+C+extensions+to+Tcl+9 says:

"Tcl_Size" itself doesn't need to be provided as long as you update the extension to the latest tclconfig release. TEA (latest tcl.m4/rules.vc files) takes care of providing an appropriate preprocessor #define for Tcl_Size.

but we assume this has not happened.
