<https://core.tcl-lang.org/tips/doc/trunk/tip/476.md>:

    "Whenever possible, typedef Tcl_WideInt to be equal to long long,
    even on platforms where long has the same size as long long."

I would be OK with throwing away TCL_WIDE_INT_TYPE.
Changing it would be a binary incompatible changes, and too
many internal constructs would break if
sizeof(Tcl_WideInt) > sizeof(long long)

Hope this helps,
