# Makefile for GNU make, possibly nmake
# Add strlcpy(3), strlcat(3) and reallocarray(3) to the link either
# by setting DPADD (dependency) and LDADD (link object) accordingly
# or by adding the respective files and uncommenting OBJS2/OBJS3 as
# needed; uncommenting DEFS2/DEFS3 may also be necessary (even with
# LDADD=-lbsd); glibc ships reallocarray now but still not strlfun.
