# 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)
