+ 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, Python must first be compiled and installed on
+ the build host.  The configure script will use `cc' and `python', or
+ environment variables CC_FOR_BUILD or PYTHON_FOR_BUILD, eg:
+ 
+    CC_FOR_BUILD=gcc-3.3 \
+    PYTHON_FOR_BUILD=python2.4 \
+    .../configure --build=i686-linux --host=i586-mingw32
+ 
+ Cross compiling has been tested under linux, 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, i586-mingw32-ranlib, ...),
+ - CC, CXX, AR, and RANLIB must be undefined when running configure,
+   they will be auto-detected.
+ 
+ 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 .
