Thank you for your quick reply. 
If I understand this correctly, it looks like I will have to spawn a
process that runs a windows batch file that processes the command line
parameters and synthesizes the names of the log file that LilyPond used
to create and then calls LilyPond with re-direction of the output. I'm
not sure that this can be done without a terminal popping up to annoy
the user.

However I think what this says is that the current problem of a
terminal popping up and blocking progress is due something else that
has changed:
there used to be an executable lilypond-windows.exe in addition to the
lilypond.exe which has also vanished. I suspect it was compiled using
the option

-mconsole

passed to gcc as this is how Denemo is compiled to avoid leaving a
terminal around that would tempt the user to kill everything by
dismissing it (Windows users are generally not familiar with
terminals).

Is there anyway of spawning a LilyPond 2.24 process on Windows now
without plaguing the user with terminals?
