Bug report

Bug description:

If python.bat %pgo_job% fails, the build silently succeeds because %ERRORLEVEL% is reset by subsequent commands inside the same parenthesized block (eager evaluation).

A proposed fix would be to split the block after @echo off, save %ERRORLEVEL% outside the block, and check it after call :Kill.

CPython versions tested on:

3.13, CPython main branch

Operating systems tested on:

Windows
