Changed, I assume for portability.

Looking at configure.in, it looks pretty safe:
if test "$ac_env_CXXFLAGS" != set; then if test "$GXX" = yes; then CXXFLAGS=-O2 else case $template in
osf) CXXFLAGS='-O4 -Olimit 2000' ;; unixware) CXXFLAGS='-O' ;; *) CXXFLAGS=
;; esac fi fi
Because CXXFLAGS is already set for freebsd/alpha, it falls through,
missing the -O2 setting.
