CFLAGS problem

["Michael H. Price II" <price_(_at_)_netdoor_(_dot_)_com>]

I'm having problems compiling a few ports due to CFLAGS not being quoted
properly.

For example, a "make -n" in /usr/ports/textproc/agrep gives the following on
my machine:

  echo "===>  Building for agrep-2.04"
  cd /usr/ports/textproc/agrep/work/agrep-2.04 && exec /usr/bin/env -i
  PATH='/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11R6/bin'
  PREFIX='/usr/local' LOCALBASE='/usr/local' X11BASE=/usr/X11R6 MOTIFLIB=''
  CFLAGS='-O2 -fno-strength-reduce ' TRUEPREFIX='/usr/local' DESTDIR=''
  EXTRA_SYS_MK_INCLUDES="<bsd.own.mk>" BSD_INSTALL_PROGRAM="install -c -s -o
  root -g bin -m 555" BSD_INSTALL_SCRIPT="install -c -o root -g bin -m 555"
  BSD_INSTALL_DATA="install -c -o root -g bin -m 444" BSD_INSTALL_MAN="install
  -c -o root -g bin -m 444" BSD_INSTALL_PROGRAM_DIR="install -d -o root -g bin
  -m 755" BSD_INSTALL_SCRIPT_DIR="install -d -o root -g bin -m 755"
  BSD_INSTALL_DATA_DIR="install -d -o root -g bin -m 755"
  BSD_INSTALL_MAN_DIR="install -d -o root -g bin -m 755" make CFLAGS=-O2
  -fno-strength-reduce -f Makefile
  touch -f /usr/ports/textproc/agrep/work/.build_done

Which results in the following error:

===>  Building for agrep-2.04
make: cannot open no-strength-reduce.
*** Error code 2

Stop in /usr/ports/textproc/agrep (line 1628 of /usr/ports/infrastructure/mk/bsd.port.mk).
