Sure.  It's just that I think we want to have a trigger whether or not 
to produce installation sets during a build, and I always thought that 
--enable-epm, despite its name and original purpose, achieved that. 
(But, it appears, it happens to achieve that only for non-Windows builds.)

Ah, good to know.  And the commands issued to do the build are just 
./autogen.sh and a no-arguments "make"?  (Btw, 
<https://wiki.documentfoundation.org/Development/ReleaseBuilds#Linux_.28same_options_for_x86_.26_x86_64.29> 
misses the manually updated flex now, IIUC, right?)

Yeah, I get the idea.

...which brings me back to my original question for a universal trigger 
whether or not to produce installation sets during a build.

Seeing that --enable-epm currently effectively fulfills that role 
everywhere but on Windows, one option would be to make it fulfill that 
role on Windows too.  (I have a local patch to do that.)

The alternative would be to introduce an explicit 
--enable-installation-sets.  Opinions, anyone?

Yes, that's my understanding, too.

Ah, there's an example of such a file, thanks.  I was pretty sure we had 
something like that, just couldn't find any in that maze of mostly empty 
directories at <http://dev-builds.libreoffice.org/daily/>.
