+ * configure.host: Incorporate host Makefile fragments by setting
+ shell variables.
+ * configure.in: Call AC_PROG_CC. Substitute CFLAGS, HDEFINES and
+ AR. Call AC_PROG_INSTALL. Substitute CC_FOR_BUILD, choosing a
+ value based on whether the code is being compiled by a cross
+ compiler. Don't substitute host_makefile_frag or frags.
+ * aclocal.m4: New file to define local AC_PROG_CC.
+ * configure: Rebuild.
+ * Makefile.in (INSTALL): Set to @INSTALL@.
+ (INSTALL_PROGRAM): Set to @INSTALL_PROGRAM@.
+ (INSTALL_DATA): Set to @INSTALL_DATA@.
+ (AR): Set to @AR@.
+ (CC): Define as @CC@.
+ (CFLAGS): Set to @CFLAGS@.
+ (CC_FOR_BUILD): Set to @CC_FOR_BUILD@.
+ (@host_makefile_frag@): Remove.
+ (ALL_CFLAGS): Change $(HDEFINES) to @HDEFINES@. Move $(CFLAGS)
+ after other options.
+ (config.status): Remove dependency upon @frags@.
+ * config/*.mh, config/README: Remove.
+
* config.bfd: Rewrite to incorporate the contents of the Makefile
fragments by setting shell variables, rather than merely returning
the name of a Makefile fragment.
