  15 # There are two options in making libm at fdlibm compile time:
  16 #       _IEEE_LIBM      --- IEEE libm; smaller, and somewhat faster
  17 #       _MULTI_LIBM     --- Support multi-standard at runtime by
  18 #                           imposing wrapper functions defined in
  19 #                           fdlibm.h:
  20 #                               _IEEE_MODE      -- IEEE
  21 #                               _XOPEN_MODE     -- X/OPEN
  22 #                               _POSIX_MODE     -- POSIX/ANSI
  23 #                               _SVID3_MODE     -- SVID
  24 #
  25 # Here is how to set up CFLAGS to create the desired libm at
  26 # compile time:
  27 #
  28 #       CFLAGS = -D_IEEE_LIBM           ... IEEE libm (recommended)
  29 #       CFLAGS = -D_SVID3_MODE  ... Multi-standard supported
  30 #                                           libm with SVID as the
  31 #                                           default standard
  32 #       CFLAGS = -D_XOPEN_MODE  ... Multi-standard supported
  33 #                                           libm with XOPEN as the
  34 #                                           default standard
  35 #       CFLAGS = -D_POSIX_MODE  ... Multi-standard supported
  36 #                                           libm with POSIX as the
  37 #                                           default standard
  38 #       CFLAGS =                        ... Multi-standard supported
  39 #                                           libm with IEEE as the
  40 #                                           default standard
  41 #
  42 # NOTE: if scalb's second arguement is an int, then one must
  43 # define _SCALB_INT in CFLAGS. The default prototype of scalb
  44 # is double scalb(double, double)
  45 #
  46
