# 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
# math.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
