I think you are correct. I misread the documentation. I thought the
comment in configure said that it would add "-g" when CFLAGS was set,
rather than that the user must add it.

I do find the default action unexpected, however. If "--enable-debug" is
not set in the configure options, configure silently removes a "-g"
that is set in CFLAGS. I would think that most folks would expect the
explicitly set CFLAGS to be unchanged, unless "--disable-debug" were to
be specifically set. (I don't know why someone would want to set "-g" in
CFLAGS, then specify "--disable-debug".)
