Document source revision and build provenance of Windows libtommath.dll in Tcl/Tk 9.0.4

Documentation

Could the source release/commit and build provenance be documented for the Windows x64 libtommath.dll supplied with CPython's Tcl/Tk 9.0.4 dependency bundle?

Public artifact references:

• cpython-bin-deps: tcltk-9.0.4.0/amd64/bin/libtommath.dll
• cpython-source-deps: tcl-9.0.4.0/libtommath/win64
• The corresponding Tcl Windows makefile

The DLL in both repositories has Git blob ID 856af88d7e51af58d705d9b187a0b151880bafee and size 81,408 bytes. It has no file/product version resource. The dynamic x64 makefile copies that prebuilt DLL instead of compiling the adjacent LibTomMath sources, so the neighboring source changelog does not by itself establish the DLL's source revision.

A pointer to the exact upstream release/commit, build recipe/toolchain, and applicable license/notice would make component attribution and advisory-version matching possible without guessing. If this information already exists, could it be linked alongside the binary dependency records?

This is a provenance/documentation request, not a report of a confirmed vulnerability. I am filing here because the binary-dependency repository has issues disabled.

Beginne mit der referenzierten tcl-9.0.4.0/win/makefile.vc sowie den amd64 libtommath.dll- und win64-Quellpfaden und verfolge dann, wie der dynamische x64-Build die vorkompilierte DLL verarbeitet. Als abgeschlossen gilt die Verknüpfung mit dem exakt entsprechenden Upstream-Quellrelease oder Commit, die Dokumentation des Build-Rezepts und der Toolchain sowie die Erfassung der geltenden Lizenz oder des Hinweises neben den Datensätzen der binären Abhängigkeiten.
