New submission from Mark Dickinson <dickinsm at gmail.com>:
When doing a debug build of Python with gcc, without any previous setting of CFLAGS, the '-O2' flag is now automatically included.
This behaviour started in r79218.
It would be nice to restore the original behaviour, if possible, since the optimization causes difficulties when debugging. One solution would be to add '-O0' to OPT for debug builds (on gcc), as in the attached patch. You then get compiler flags including:
"-g -O2 -g -O0"
which is somewhat ugly, but the -O0 overrides the -O2 (I think). Does this seem like a reasonable solution?
