  17 # There are two options in making libm at fdlibm compile time:
  18 #       _IEEE_LIBM      --- IEEE libm; smaller, and somewhat faster
  19 #       _MULTI_LIBM     --- Support multi-standard at runtime by
  20 #                           imposing wrapper functions defined in
  21 #                           fdlibm.h:
  22 #                               _IEEE_MODE      -- IEEE
  23 #                               _XOPEN_MODE     -- X/OPEN
  24 #                               _POSIX_MODE     -- POSIX/ANSI
  25 #                               _SVID3_MODE     -- SVID
  26 #
  27 # Here is how to set up CPPFLAGS to create the desired libm at
  28 # compile time:
  29 #
  30 #       CPPFLAGS = -D_IEEE_LIBM         ... IEEE libm (recommended)
  31 #       CPPFLAGS = -D_SVID3_MODE        ... Multi-standard supported
  32 #                                           libm with SVID as the
  33 #                                           default standard
  34 #       CPPFLAGS = -D_XOPEN_MODE        ... Multi-standard supported
  35 #                                           libm with XOPEN as the
  36 #                                           default standard
  37 #       CPPFLAGS = -D_POSIX_MODE        ... Multi-standard supported
  38 #                                           libm with POSIX as the
  39 #                                           default standard
  40 #       CPPFLAGS =                      ... Multi-standard supported
  41 #                                           libm with IEEE as the
