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.

從所引用的 tcl-9.0.4.0/win/makefile.vc 以及 amd64 libtommath.dll 和 win64 原始碼路徑開始，接著追蹤動態 x64 建置如何處理預先建置的 DLL。完成條件是連結至完全對應的上游原始碼發行版本或 commit、記錄建置配方與工具鏈，並將適用的授權條款或 notice 與二進位相依性記錄一併記錄。
