that contains:
* Removes remaining (now illegal) references to $(SRC) from a couple of
Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
libbsp/*/configure.ins (A minor bug in previous implementations, which
only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
handling)
The patch below actuallly consists of two patches:
1) moving librpc to c/src/librpc similar to what has been done to librtems++
2) reworked configure scripts, many safety and dependency checks added to
aclocal/*.m4 macros + configuration fixes.
To apply:
mkdir c/src/librpc
mkdir c/src/librpc/src
cp c/src/lib/librpc/*.c c/src/librpc/src
cp c/src/lib/librpc/Makefile.in c/src/librpc/src
mkdir c/src/librpc/include
mkdir c/src/librpc/include/rpc
cp c/src/lib/include/rpc/* c/src/librpc/include/rpc
patch -p1 < ../rtems-rc-19990820-7.diff
rm -rf c/src/lib/librpc
rm -rf c/src/lib/include/rpc
./autogen
The additional checks in aclocal/*m4 macros add rather restrictive, sometimes
unnecessarily restrictive constraints on the sequence of how macros can be
used in a configure.in script. Adding them has let my problems with some more
complicated configuration options vanish. Apparently some macros had not been
in the required order .

Now I still get some linking errors for some cpus and bsps, esp when linking
cdtest, but also at other locations:
e.g. this happens for mips64orion/p4600:

This patch addresses a few configuration issues and removes some
duplicate configuration files.
Background:
* some files used in AC_INIT were not unique enough and can lead to
problems if a user plays with configure scripts.
* the Makefile templates are independent of the target/cpu and bsp, so
the bsp dependent versions (c/src/make/Templates) are removed.
To apply:
patch -p1 < rtems-rc-19990820-3.diff
rm -f c/src/make/Templates
./autogen
ATTENTION: This patch removes several files and one directory :)
The main topic is replacing the hard-coded values for HAS_MP and
HAS_RDBG in custom/*.cfg with per-bsp configuration-time autoconf checks
(This is the patch I had mentioned before earlier this week).
CHANGES
* HAS_MP removed from custom/*.cfg, replaced with configuration time
autoconf check
* HAS_RDBG removed from custom/*.cfg, replaced with configuration-time
autoconf check
* NEW: c/src/make/bsp.cfg.in, takes configuration-time checked per-bsp
values (i.e. HAS_MP, HAS_RDBG), gets installed as
$(prefix)/<bsp>/make/bsp.cfg
* NEW: default.cfg includes bsp.cfg - this change is backward
compatible.
* IMPORT_SRC: apply VPATH instead for ts_386ex/i386ex subdirectory
Makefile.ins
* HACK: a bug in acpolish mis-handles addtions to makefile variables
which are enclosed in gmake conditionals:
c/src/lib/libbsp/m68k/ods68302/start302/Makefile.in
* Apply inline_dir, HAS_MP and HAS_RDBG for avoiding configuration of
unneeded subdirectories in various configure.in files.
* Several minor changes in Makefile.ins and configure.ins, wrt. to the
order of including *.cfg and defining Makefile variables
APPLYING THE PATCH:
patch -p1 < rtems-rc-19990709-4.diff
./autogen
This patch is an addition to "The big-patch"
CHANGES:
* FIX: c/Makefile.am: bogus comment which changed the behavior of
c/Makefile.am removed
* FIX: make/custom/ts_i386ex.cfg did not set HAS_NETWORKING correctly
(Me thinks it might have been me who added this bogus setting :-).
* NEW: removing make targets get, protos, debug_install, profile_install
* NEW: replacing clobber with distclean
* NEW: Reimplement distclean and clean as reverse depth first make
targets (adaptation to automake's behavior)
* NEW: removing RCS_CLEAN from make distclean (tools/build/rcs_clean is
still in - remove it?)
* NEW: "$(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
