made no attempt to divide the comments up and place them with just
the appropriate files. Here is an excerpt from Ralf's email:
Changes including comments on changes I made after cycling through
all the targets:
* Added ranlib support. Now all targets use "ranlib" instead of "ar -s"
to build an index for a library. If ranlib isn't detected during
configuration, check if ar -s is working and try "ar -s" instead of
* Removed $(XXX_FOR_TARGET) from make/target.cfg.in, use $(XXX) instead now.
* gcc-target-default.cfg: LINK_XXXX-defines reworked to solve the -l
problem under posix (cf gcc-target-default.cfg)
* rtems-glom replaced by Makefile-rules inside of the wrapup/Makefile.in
that has been using rtems-glom until now.
* Removed CCC and friends in gcc-target-default.cfg, as they have been
breaking CXX support.
* Removed CONFIG.$(TARGET_ARCH).CC lines from several custom/*.cfg
files, because this is now set in custom/default.cfg.
* Added aclocal/ar-s.m4, check whether "ar -s" is working
* Added aclocal/cygwin.m4 and aclocal/exeext.m4.
* Reworked aclocal/canonicalize-tools.m4: Added ar -s check; fixes for
problems when XXX_FOR_TARGET is given via environment variables (didn't
work for gcc until now), adding cygwin check, improved autoconf-cache
handling.
* Removed -l from make rule dependencies. LINK_LIBS is now allowed to
contain -L and -l. LINK_OBJS and LINK_FILES must not contain -L or -l.
gcc28 make-exe rules now link using $(LINK_OBJS) $(LINK_LIBS) => Almost
all custom/*.cfg are modified. This is very likely to break something
because of typos or having missed to edit a file.
Open problems, known bugs, things I didn't do:
* custom/p4000.cfg seems to be out of date and requires to be reviewed.
(JRS NOTE: It is subordinate p4650 and p4600 -- both of which build ok
after minor changes.)
* custom/psim.cfg needs to be reviewed, I added some changes to it, I am
insecure about.
(JRS NOTE: psim had a minor problem endif/endef swapped but runs fine.)
* rtems-glom.in can now be removed.
* gcc*.cfg files "make depend" rules don't honor language specific flags
(e.g CXXFLAGS is ignored for *.cc) - Nothing to worry about now, but may
cause problems for hosts/targets not using gcc or rtems-add-ons that use
external packages.
* AFAIS, the no_bsp BSP can't be build anymore, i.e. configure refused
to configure for it whatever I tried.
* The toplevel and toplevel+1 README files are quite out-dated
* cygwin.m4 isn't of much use for rtems. In most cases (cf.
aclocal/*.m4) it is worked around by directly using $host_os. I think
I'll remove it soon after the next snapshot
* Before release the cygwin patch needs to be tested under cygwin. I may
have broken/missed something (esp. the sed-pattern to convert \\ into /
may be broken).
* You should try to build/run the posix-BSP under solaris - I don't
expect problems, but I am not 100% sure, esp. with regard to ranlib/ar -s.
* You should consider to convert all make/compilers/*.cfg files into
make/compilers/*.cfg.in files and let autoconf generate the *.cfg. This
may help getting rid of some if/then/else statements and help
hard-coding some defines into those files in future and shouldn't
disturb now.
* Not having installed libc.a/libm.a on a host may still break building
rtems, esp. when using -disable-gcc28 as the gcc27-configuration scheme
directly accesses libc.a and libm.a. The problem should not appear when
using gcc28 because it references libc/libm only through -lc and -lm
which may be static or dynamic (I didn't test this).
* shgen is not yet included (I didn't yet have enough time to integrate it).
* I know about a few more configure-probs (esp. cross-checking
--enable-* flags).
+ warn/refuse to configure when --enable-libcdir and
--enable-gcc28 are given.
+ force --enable-libcdir when --disable-gcc28 is given
* Replaced KSHELL with @KSH@ in some shell scripts generated by configure.in.
* Added a dependency to aclocal/*.m4 in the toplevel Makefile => configure
and aclocal.m4 will now be rebuild when any aclocal/*.m4 file is changed
* Some changes to aclocal/gcc-pipe.m4 and aclocal/gcc-specs.m4
* Replaced i[[3456]]86-unknown-freebsd2.[[12]] with i[[3456]]86-*freebsd2.*
in configure.in, as I suppose there might exist a variety of valid vendors
(2nd field of the name-tripple)
* Disabled override MAKEFLAGS in toplevel Makefile.in - Potential
side-effects are not really clear to me.
* In mvme162.cfg, $(LINK_LIBS) is missing in the CC line in gcc28's make-exe
rule (yet another one I missed to edit). Just append $(LINK_LIBS) to
the "CC" line, like I hopefully did to ALL other custom/*.cfg files.
* the problem with mvme162lx.cfg is a follow-up problem of the
mvme162.cfg-bug.
* mvme162/console and idp/console had variables named Buffer which
conflicted with similarly named variables in some tests.

CFLAGS_$(TARGET_VARIANTS). This makes sure that -Wall appears
before any individual warnings are disabled during "debug" builds.
