 That's what I thought too, but reality didn't seem to quite match. Most 
notably, after I extended --enable-symbols to be selective about which 
modules get the -g, it ended up with 
http://cgit.freedesktop.org/libreoffice/core/commit/?id=c8fa9bd8849f0503b3803465e8ce119581e11e33, 
which moved the selective -g to --enable-debug (while claiming in the commit 
log message that it's unlikely somebody actually wants such a feature). And 
in general, in every single discussion about these 3 options there was always 
somebody who was confused about them, so removing one of these generically 
named options seemed like a good thing.

 But I'm not dead set against --enable-symbols, this just seemed the simplest 
solution given the circumstances. If you manage to get the story right about 
what these 3 options do (4 options, if the story doesn't include 
moving --enable-selective-debuginfo functionality to --enable-symbols), go 
ahead.
