# You probably want to take -DREDEBUG out of CFLAGS, and put something like
# -O in, *after* testing (-DREDEBUG strengthens testing by enabling a lot of
# internal assertion checking and some debugging facilities).
# Put -Dconst= in for a pre-ANSI compiler.
# Do not take -DPOSIX_MISTAKE out.
# REGCFLAGS isn't important to you (it's for my use in some special contexts).
# If you have a pre-ANSI compiler, put -o into MKHFLAGS. If you want
# the Berkeley __P macro, put -b in.
# Flags for linking but not compiling, if any.
# Extra libraries for linking, if any.
# Internal stuff, should not need changing.
