 Hello, All!
 Тут как-то пролетало насчет опций gcc CFLAGS= -O2 -march=<cpu>. Почитал
 я etc/defaults/make.conf, и подумалось, что если его поместить в
 etc/make.conf с включенными такими опциями, то он будет отрабатывать их
 и включать при каждом make install. Я прав? Вот на ваше усмотрение
 созданный etc/make.conf:
 -----------------------------------------------------
 # The CPUTYPE variable controls which processor should be targeted for
 # generated code.  This controls processor-specific optimizations in
 # certain code (currently only OpenSSL) as well as modifying the value
 # of CFLAGS to contain the appropriate optimization directive to gcc.
 # The automatic setting of CFLAGS may be overridden using the
 # NO_CPU_CFLAGS variable below.
 # Currently the following CPU types are recognized:
 #   Intel x86 architecture:
 #       (AMD CPUs) k7 k6-2 k6 k5
 #       (Intel CPUs) p4 p3 p2 i686 i586/mmx i586 i486 i386
 #   Alpha/AXP architecture: ev6 pca56 ev56 ev5 ev45 ev4
 
 CPUTYPE=p3            #процессор - celeron2
 
 #NO_CPU_CFLAGS= true # Don't add -march=<cpu> to CFLAGS automatically
 #NO_CPU_COPTFLAGS=true # Don't add -march=<cpu> to COPTFLAGS
 automatically
 #
 # CFLAGS controls the compiler settings used when compiling C code.
 # Note that optimization settings above -O (-O2, ...) are not
 recommended
 # or supported for compiling the world or the kernel - please revert any
 # nonstandard optimization settings to "-O" before submitting bug
 reports
 # to the developers.
 
 CFLAGS= -O2 -pipe
 
 # BDECFLAGS are a set of gcc warning settings that Bruce Evans has
 suggested
 # for use in developing FreeBSD and testing changes.  They can be used
 by
 # putting "CFLAGS+=${BDECFLAGS}" in /etc/make.conf.  -Wconversion is not
 # included here due to compiler bugs, e.g., mkdir()'s mode_t argument.
 
 BDECFLAGS= -W -Wall -ansi -pedantic -Wbad-function-cast -Wcast-align \
   -Wcast-qual -Wchar-subscripts -Winline \
   -Wmissing-prototypes -Wnested-externs -Wpointer-arith \
   -Wredundant-decls -Wshadow -Wstrict-prototypes -Wwrite-strings
 
 # To compile just the kernel with special optimizations, you should use
 # this instead of CFLAGS (which is not applicable to kernel builds
 anyway).
 # There is very little to gain by using higher optimization levels, and
 doing
 # so can cause problems.
 
 COPTFLAGS= -O -pipe
 
 -----------------------------------------------------
 Как считаете? Прокатит? Hе придется каждый раз при make install их
 включать руками? Кстати, как это сделать?(В смысле, формат комстроки
 включения опций -O2 -march=<cpu> для make install).
 With best regards, Kuziakin F.S.
