# To profile, put -DPROF in DEFS and -pg in CFLAGS, and recompile.

# Patch over a misfeature in the bsd.prog.mk that comes with the BSD
#  make installed by at least one version of Linux.  (It sets CFLAGS to
#  -O2 -fno-strict-aliasing -pipe, leaving no sane way to just turn off
#  optimization - to turn off -O2 you have to replace CFLAGS, meaning
#  you have to either somehow divine what other options are in it or be
#  willing to trash them willy-nilly.  Fortunately, the former is
#  relatively easy.  Mercifully, it sets it with ?=, so we can define
#  it here and not get it trashed by bsd.prog.mk.)
