# --------------------------------------------------------------------
# System Dependent Configuration:
#   Choose a pre-packaged set of options below, or roll your own.
#   The relevant options are as follows:
#
# * To use under unix, you MUST define '-DUNIX' in DEFS.
#
# * If you have the `PW' library which includes the regular-expression
#   funcions regcmp(3) and regex(3), then use `-DREGEX' in DEFS, and
#   `-lPW' in LIBS.  If you have the regular-expression functions
#   re_comp(3) and re_exec(3), use `-DRE_EXEC' in DEFS.  If you don't
#   have any regular-expression functions, don't add either to DEFS.
#
# * If you do not have the 4.2 directory access libraries, add `-lndir'
#   to LIBS, and define `-DNDIR' in DEFS. 
#
# * If your string libraries have index(3) and rindex(3) instead of
#   strchr(3) and strrchr(3), use `-DRINDEX' in DEFS.
#
# * If your compiler chokes on pointers to functions returning void,
#   use `-Dvoid=int' in DEFS.
#
# * If you have setlinebuf(3) in your stdio to set line-buffering on
#   a stream, use `-DERRLINEBUF' in DEFS.
#
# * If you have a System-III/V terminal driver, define `TERMIO' in DEFS.
#
# * If you have ranlib(1), define `RANLIB' as such.  If you don't have
#   it, set `RANLIB' to something harmless like `@:', or `echo'
