clang does not recognize the -no-cpp-precomp option and generates
a warning. -no-cpp-precomp is an obsolete Apple-specific gcc option,
which last had any effect in gcc 3.1 for Jaguar.
Since we cannot build for Jaguar anyway, the configure test added
in 8412a400e92d5cbcd is not needed.

Requires own build of wxMac for wx to work:
$ arch_flags="-arch i386"
$ ./configure CFLAGS="$arch_flags" CXXFLAGS="$arch_flags" \
CPPFLAGS="$arch_flags" LDFLAGS="$arch_flags" OBJCFLAGS="$arch_flags" \
OBJCXXFLAGS="$arch_flags" --prefix=/usr/local \
--with-macosx-sdk=/Developer/SDKs/MacOSX10.6.sdk \
--with-macosx-version-min=10.6 --enable-unicode --with-opengl
$ make
$ sudo make install
- and we have macports gcc 4.5 in /opt/local/bin, so we configure
and build OTP like this for 32bit (which is required for wx):
$ cd $ERL_TOP
$ PATH=/usr/local/bin:$PATH CC=/opt/local/bin/gcc-mp-4.5 CXX=/opt/local/bin/g++-mp-4.5 ./configure --enable-m32-build
$ MAKEFLAGS="-j6" PATH=/usr/local/bin:$PATH make

improvements.
Most notable:
Lots of cross compilation improvements. The old cross compilation
support was more or less non-existing as well as broken. Please,
note that the cross compilation support should still be
considered as experimental. Also note that old cross compilation
configurations cannot be used without modifications. For more
information on cross compiling Erlang/OTP see the
$ERL_TOP/xcomp/README file.
Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D
ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed.
For more information see the $ERL_TOP/README file.
Documentation of the release target of the top Makefile. For more
information see the $ERL_TOP/README file.
make install now by default creates relative symbolic links
instead of absolute ones. For more information see the
$ERL_TOP/README file.
$ERL_TOP/configure --help=recursive now works and prints help for
all applications with configure scripts.
Doing make install, or make release directly after make all no
longer triggers miscellaneous rebuilds.
Existing bootstrap system is now used when doing make install, or
make release without a preceding make all.
The crypto and ssl applications use the same runtime library path
when dynamically linking against libssl.so and libcrypto.so. The
runtime library search path has also been extended.
The configure scripts of erl_interface and odbc now search for
thread libraries and thread library quirks the same way as erts
do.
The configure script of the odbc application now also looks for
odbc libraries in lib64 and lib/64 directories when building on a
64-bit system.
The config.h.in file in the erl_interface application is now
automatically generated in instead of statically updated which
reduces the risk of configure tests without any effect.

new mandatory configuration variable that replaces all other
previously mandatory configuration variables, and better
documentation. Note that old cross compilation configurations
cannot be used without modifications.
For more information see the $ERL_TOP/xcomp/README file.
