# Note: this Makefile may need modified depending upon which type of machine

# uncomment RESOLV if your machine has libresolv.a in /lib or /usr/lib
RESOLV=-lresolv
 
# uncomment MALLOC* if you wish to use BSD malloc or Smalloc.
#   Both of these require the sbrk() system call.  Be sure to read the
#   comments in the bsdmalloc.c file before deciding on BSDMALLOC.
#   note: These mallocs may not work correctly on the NeXT or other systems
#   that don't fully support sbrk().  It is okay not to use either of these
#   two mallocs in which case you will get system malloc (read the comments
#   in options.h for choices on malloc statistics and debugging).
#
# uncomment this line for BSDmalloc
# (fast but high overhead)
#MALLOC=bsdmalloc.c
# uncomment this line for SMALLOC
# (slower than bsdmalloc, faster than most system mallocs, least overhead)

# uncomment STR if your machine is missing memcpy(), memset(), strtol(),
# and strcspn().  (ie Sequent Dynix/3)
