How can that happen?  The following lines from configure.bat
unconditionally create it from config.nt and add 2 lines to it:

    copy config.nt config.tmp
    echo. >>config.tmp
    echo /* Start of settings from configure.bat.  */ >>config.tmp

And even if config.tmp were indeed missing, the `fc' command that is
run by configure.bat, viz.:

    fc /b config.tmp ..\src\config.h >nul 2>&1
    if errorlevel 1 goto doCopy

should have forced the branch to doCopy, because `fc' exits with
status of 2 if one of its file arguments does not exist.  Then the
copy command:

    :doCopy
    copy config.tmp ..\src\config.h

should have complained like this:

    The system cannot find the file specified.

if config.tmp did not exist.  Do you see such an error message when
configure.bat runs?

Hmm... I think I see the problem.  The second line of this
fragment:

    fc /b paths.h ..\src\epaths.h >nul 2>&1
    if errorlevel 0 goto dontCopy

should say instead

    if not errorlevel 1 goto dontCopy

Could you try this change, please?
