#should be OK in most situations:
#CFLAGS= -O

# HP/UX 9.0X optimized code
#CFLAGS= +O3 +Oaggressive +Olibcalls -Aa -D_POSIX_SOURCE -DCHECK +FP VZOUiD
# HP/UX 9.0X debugging

# nice for gcc
CFLAGS= -O3 -Wall -pedantic -ansi
#CFLAGS= -g -Wall -pedantic -ansi

# Option -DCHECK checks for numerical problems during rounding of numbers.
# It will slow things down a bit.
# You can add a -DREAL=<float type> to the CFLAGS, to change the default float
# type used in lp_solve (double) to float or 'long double'. However, type float
# might be fast on your computer, but it is not accurate enough to solve even
# moderately sized problems without running into numerical problems.
# The use of long doubles does increase the numerical stability of lp_solve,
# if your compiler actually implements them with more bits than a double. But
# it slows down things quite a bit.
