Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:
This patch is an addition to "The big-patch" CHANGES: * FIX: c/Makefile.am: bogus comment which changed the behavior of c/Makefile.am removed * FIX: make/custom/ts_i386ex.cfg did not set HAS_NETWORKING correctly (Me thinks it might have been me who added this bogus setting :-). * NEW: removing make targets get, protos, debug_install, profile_install * NEW: replacing clobber with distclean * NEW: Reimplement distclean and clean as reverse depth first make targets (adaptation to automake's behavior) * NEW: removing RCS_CLEAN from make distclean (tools/build/rcs_clean is still in - remove it?) * NEW: "$(RM) Makefile" added to make distclean (adaptation to automake's behavior) * NEW: "$(RM) config.cache config.log" to CLOBBER_ADDITIONS in [lib|exec|tests]/Makefile.in (adaptation to automake's behavior) * NEW: "$(CLEAN_PROTOS)" removed (Not used anywhere) * NEW: binpatch.c moved from i386 bsp tools to tools/build (AFAIS, binpatch is not specific to the pc386 BSP at all) * NEW: AC_EXEEXT added to all configure scripts which contain AC_PROG_CC (Cygwin support) * NEW/Experimental: An experimental implementation of temporary installation tree support in libbsp/i386/pc386/tools/Makefile.am, based on dependency tracking with make, instead of applying INSTALL_CHANGE. REMARK: * This patch is small in size, but changes the behavior of "make clean|distclean|clobber" basically. * This patch does not alter building/compiling RTEMS, ie. there should be no need to rerun all "make all" building tests. KNOWN BUGS: * make RTEMS_BSP="..." distclean in c/ runs "make distclean" in BSPs subdirectories passed through RTEMS_BSP and in "c/." only, but does not descend into other BSP subdirectories previously configured with different settings of make RTEMS_BSP="...". => Workaround: always use the same setting of RTEMS_BSP when working inside the build-tree. * "make [distclean|clean]" do not clean subdirectories, which have been configured at configuration time, but which are not used due to make-time configuration (e.g. macros/networking/rdgb subdirectories). This will problem will vanish by itself when migrating from make-time to configuration-time configuration APPLYING THE PATCH mv c/src/lib/libbsp/i386/pc386/tools/binpatch.c tools/build patch -p1 < rtems-rc-19990709-2.diff autogen
