yes
The default option of NetBSD-i386 is "- O2",
when there is no specification in libdv/Makefile.

yes
"-O" appears like the following descriptions after "-O2" 
and "-O" is given to priority in all the environments,
when "CFLAGS+=-O" is added.

/bin/sh ../libtool --silent --mode=link cc  -I/usr/pkg/include/gtk-1.2 -I/usr/pk
g/include/glib/glib-1.2 -I/usr/pkg/lib/glib/include -I/usr/X11R6/include -O2 -O

However, I do not want to lower the optimization level on NetBSD-i386.
