RE: [HACKERS] --enable-debug

From

When I initially mentioned this, I had tried to debug, only to find that
there were no symbols.  So I tried the standard autoconf option, which is
--enable-debug, to get some symbols.  I'm not particularly concerned about
--cassert, but --enable-debug is the standard autoconf option, and most
people (developers) are aware of it.  If it's just a synonym for --cassert,
well, I don't really care.  I just want some symbols to debug with.  I
landed up fixing it by setting 
CC=gcc -g -Wall

or something, and recompiling.

gmake COPT="-g" all (after a clean) worked for me...that leave -O2 on,
though.  Gcc seems to do a reasonably good job anyway.

We are doing -Wall on Linux, BTW, in case there's any doubt (Tom mentioned
it was used on his platform but I think he's an HP-UX kinda guy).  At
least, when I do a make on my RH 6.1 box with the current sources "-Wall"
is on.
