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). | |
