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.
9 (AM_BINUTILS_WARNINGS): Introduce ac_cpp_for_build variable
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
