1 # You probably want to take -DREDEBUG out of CFLAGS, and put something like
2 # -O in, *after* testing (-DREDEBUG strengthens testing by enabling a lot of
3 # internal assertion checking and some debugging facilities).
4 # Put -Dconst= in for a pre-ANSI compiler.
5 # Do not take -DPOSIX_MISTAKE out.
6 # REGCFLAGS isn't important to you (it's for my use in some special contexts).
