I see. That's okay, then, thanks for the explanation.

Now that I got to compilation, "make -j2" freezes the process soon after 
start (I've tried it several times), here's the whole log:

$ make -j 2

Is that what is meant by not "supporting parallel execution"?

Non-parallel "make" starts differently (!) and completes the build fine.

I think someone mentioned that this way of building would be faster, but 
configuration takes longer than with configure.bat, and compilation 
seems to take about the same amount of time.

configure.bat took ~15 seconds, msysconfig.sh takes a couple of minutes, 
the following compilation is about the same, I think.
autogen.sh takes some time, too.

Speaking of stability, I've seen it crash a few times during exit, 
around the time it complains about inability to write ACL. Haven't been 
able to reproduce this under gdb, so far.
