broken buildkernel (scsi_low and -Os) and duplicate manpages
Hi, Building the kernel with CFLAGS=-Os breaks when compiling module scsi_low. Sorry no output available. Placing CFLAGS+= -O in the Makefile fixes the problem. Last build with -O2 did work (for everything, world, kernel and ports).>From my research it appears the -Os produces code faster than -O2 andgenerally slower than -O3 but the smallest binary (and quicker compile times), does anyone have a better understanding of such things (performance and -O? flags). When doing an installworld DEST=? it fails twice when trying to install duplicate man pages: 1) lib/ncurses/ncurses: tputs.3 2) share/man/man9: rman_fini.9 David

Thanks! rafan@ (CCed) did the last few ncurses updates.
