+Cross Compiling
+---------------
+
+Python can be cross compiled by supplying different --build and --host
+parameters to configure.  Python is compiled on the "build" system and
+executed on the "host" system.  Cross compiling python requires a
+native Python on the build host, and a natively compiled tool `Pgen'.
+
+Before cross compiling, the correct version of Python must be compiled
+and installed on the build host.  The configure script will use `cc'
+and `python', or environment variables PYTHON_FOR_BUILD, eg:
+
+
+  PYTHON_FOR_BUILD=python2.5
+
+  # set these values according to your cross-compiler setup
+  PATH="$HOME/cross-target/freebsd-x86/usr/cross/bin:$PATH"
+
+  # headers & libraries for target system
+  CROSS_ROOT=$HOME/cross-target/freebsd-x86/
+
+  # supply all settings not correctly detected by configure.
+  # This can also be put a config.cache file
+  ac_cv_file__dev_ptmx=no
+  # .... insert more relevant settings
+  
+  export CROSS_ROOT PATH PYTHON_FOR_BUILD \
+  	 ac_cv_file__dev_ptmx  
+  
+  configure --host=i686-freebsd4 --with-system-ffi
+  make 
+
+   
+Cross compiling has been tested under linux. Your mileage may vary for
+other platforms.
+
+A few reminders on using configure to cross compile:
+- Cross compile tools must be in PATH,
+- Cross compile tools must be prefixed with the host type
+  (ie i586-mingw32-gcc, powerpc-darwin8-ranlib, ...),
+- CC, CXX, AR, and RANLIB must be undefined when running configure,
+  they will be auto-detected.
+- Autoconf must be stopped from autodetecting definitions for the
+  build machine.  This is easiest done by creating a config.cache
+  that overrides ac_cv_* variables appropriately.
+
+If you need a cross compiler, Debian ships several several (eg: avr,
+m68hc1x, mingw32), while dpkg-cross easily creates others.  Otherwise,
+check out Dan Kegel's crosstool: http://www.kegel.com/crosstool .
