Hello Phillip,

at the moment I add "CFLAGS_OPT = -g3 -Og" to UserConf.mk in the application
directory and also on the library directory when library debug is needed.

Otherwise you can add cm3-gccdbg entries on conf/tools.nut. All those
Makedefs.cm3-gccdbg still compile with -O0, while recent compilers allow -Og
resulting in much smaller, but still debuggable code.

Bye
