# This makefile is designed to make only the bp program AND TO KEEP
# all the .obj files, so you can apply changes to one file without
# recompiling all the others.
#
# Below, where I say 32-bit floating point or 64-bit floating point,
# note that all the programs use some floating point instructions even
# the integer versions, bp and sbp.  In standard UNIX C all floating
# point arithmetic is done as double so using double values actually is
# faster than using float values (because all the conversions take
# time).  To use float rather than double define FLOAT like so:  -DFLOAT
#
# To get the compiler to use 32-bit DOS settings include: -DDOS32
# To get the compiler to use 16-bit DOS settings include: -DDOS16
#
# If you want bp to use the exact derivative when D != 1 when computing
# weight changes use: -DEXACTDERIV.  There is really no reason to do
# this unless you are a purist.  The originators of the method used a
# value for eta that is divided by D and this cancels the D you get by
# doing the exact derivative so you are in good company if you also skip
# it.  Plus you also save the time required for a floating pointing
# multiply.
#
# Below are the settings I've been using for Zortech C 3.1.  The -f flag
# in the Zortech CFLAGS forces hardware floating point instructions to
# be generated. This flag also has the compiler generate code compatible
# with the IEEE standard 754 where checks are make that comparisons
# involving NaNs are handled correctly.  To avoid these checks you can
# use -ff and the code will be around 1.6% faster on a 486/33.  Zortech
# 3.0 does not have the -ff option.  The -o is for optimize, -m is used
# to give the memory model, -4 for a 486, -3 for a 386, -2 for a 286.
#
# use the following line for DOS/ZORTECH (486)
CFLAGS= -mx -4 -f -DFLOAT -DDOS32
# use the following line for DOS/ZORTECH (386)
#CFLAGS= -mx -3 -f -DFLOAT -DDOS32
# use the following line for DOS/ZORTECH (286)
#CFLAGS= -mz -2 -f -DFLOAT -DDOS16
# use the following line for DOS/ZORTECH (8088) large memory model
#CFLAGS= -ml -f -DFLOAT -DDOS16
