   4 Subject: [PATCH 2/2] When building target binaries, ensure that the warning
   5  flags selected for the command line match the target compiler.
   6
   7 bfd     * warning.m4 (AC_EGREP_CPP_FOR_BUILD): Introduce macro
   8         to verify CC_FOR_BUILD compiler.

  10         and add CC_FOR_BUILD compiler checks.
  11         * Makefile.in: Regenerate.
  12         * configure: Likewise.
  13         * doc/Makefile.in: Likewise.
  14
  15 binutils        * Makefile.am: Replace AM_CLFAGS with AM_CFLAGS_FOR_BUILD
  16         when building with CC_FOR_BUILD compiler.
  17         * Makefile.in: Regenerate.
  18         * configure: Likewise.
  19         * doc/Makefile.in: Likewise.

  27         * testsuite/Makefile.in: Likewise.
  28
  29 gprof   * Makefile.in: Regenerate.
  30         * configure: Likewise.
  31
  32 ld      * Makefile.in: Regenerate.
