# There are two options in making libm at fdlibm compile time:
# 	_IEEE_LIBM 	--- IEEE libm; smaller, and somewhat faster
#	_MULTI_LIBM	--- Support multi-standard at runtime by 
#			    imposing wrapper functions defined in 
#			    fdlibm.h:
#				_IEEE_MODE 	-- IEEE
#				_XOPEN_MODE 	-- X/OPEN
#				_POSIX_MODE 	-- POSIX/ANSI
#				_SVID3_MODE 	-- SVID
#
# Here is how to set up CFLAGS to create the desired libm at 
# compile time:
#
# 	CFLAGS = -D_IEEE_LIBM		... IEEE libm (recommended)
#	CFLAGS = -D_SVID3_MODE	... Multi-standard supported
#					    libm with SVID as the 
#					    default standard
#	CFLAGS = -D_XOPEN_MODE	... Multi-standard supported
#					    libm with XOPEN as the 
#					    default standard
#	CFLAGS = -D_POSIX_MODE	... Multi-standard supported
#					    libm with POSIX as the 
#					    default standard
#	CFLAGS = 			... Multi-standard supported
#					    libm with IEEE as the 
#					    default standard
# 
# NOTE: if scalb's second arguement is an int, then one must
# define _SCALB_INT in CFLAGS. The default prototype of scalb
# is double scalb(double, double)
#


#
# Default IEEE libm
#
CFLAGS = -D_IEEE_LIBM
