Correct. But in Gentoo I had to end up writing an explicit guide about
it as people (both upstream developers and users) tend to mix up the two
things: http://www.gentoo.org/proj/en/qa/backtraces.xml

Unfortunately there are a number of packages that do something like
(pseudo-autoconf — I know it's broken)

AC_ARG_ENABLE([debug], , [CFLAGS="-O0 -g3 -DDEBUG"], [CFLAGS="-O2 -g0
-DNDEBUG"])

which is a pain for us to manage (and we usually end up removing and
just handling the debug handling on our side.
