Adding -DEBUGGING in CONFIGURE_ARGS activates debug code, -DEBUGGING=-g passes -g in CFLAGS (only -g is supported), and -DEBUGGING=both does... both. This is a bit confusing. IMO DEBUG=-g should only add -g and disable executable stripping, but not change the code that is built. So use -Doptimize which lets us pass arbitrary compiler flags (eg -g3), just like DEBUG does in our system Makefiles. Hints and ok afresh1@
$OpenBSD: README,v 1.2 2016/09/03 22:32:04 benno Exp $ This directory contains software that is Gigantic and Nasty but Unavoidable. Some, but not all, of the software in this subtree follows special rules, i.e. licences other than BSD. So: - check the history of external code before importing it. - for GPL software be ready to arrange for copyright papers somewhat in advance if you want to work on it (the FSF takes a few months to process these). Otherwise, changes might not make it to the main distribution, and may need some further maintenance over time, or risk getting lost. Some internal changes are acceptable, but OpenBSD can't afford to maintain a complete separate toolchain on its own.
