# Linux uses GNU make and FreeBSD uses Berkely make. The following lines
# only work in Linux. Possible solutions in FreeBSD:
#    a) use 'gmake'; b) comment out the next 3 lines, starting with 'ifeq'
#        c) build with 'make -f Makefile.freebsd'
# In Linux one can install bmake (but that won't help here).
