# RANDFLAGS controls whether all 53 bits of mantissa are used. For 32 bits
# (~50% faster) use the following:
# 	make RANDFLAGS=
# for 53 bits use:
#	make RANDFLAGS=-DALLBITS
# The default is 53 bits.
# There are special optimizations for X86 architecture.  These are turned
# on automatically for -Di386, which is the default for gcc and icc on x86
# architectures, or for -DHAVE_X86_32.  You can override this by adding 
# -DUSE_X86_32=1 to enable or -DUSE_X86_32=0 to suppress onto the RANDFLAGS. 
# Enabling it will give incorrect results for BIG_ENDIAN architectures!  
# Also, it is important to choose the correct optimization level and CPU 
# type for X86 to get maximum performance.  The following works well for me:
#	CFLAGS="-O2 -march=i686" make
# Note that -O3 is much slower than -O2 for me.
