The previous problem ( http://usalug.org/pastebin/pastebin.php?show=392 ) is 
solved with gcc (GCC) 4.1.0 20060304 (Red Hat 4.1.0-3), but with gcc32 (GCC) 
3.2.3 20030502 (Red Hat Linux 3.2.3-55.fc5) the following problem arise:

g++32 -g -I /boost_1_33_1/ -std=c++98 -pedantic main.cpp -o car_assembler
In file included from main.cpp:17:
/boost_1_33_1/boost/statechart/transition.hpp:48: no class template named `
   no_context' in `boost::statechart::detail'
main.cpp:38: object `<expression error>' cannot be used as template argument
main.cpp:38: warning: ISO C++ forbids declaration of `reactions' with no type
make: *** [debug32] Error 1

There is another problem. The full code can be found here: 
http://usalug.org/pastebin/pastebin.php?show=411

If you define some post_event, the following error occures  with gcc (GCC) 
4.1.0 20060304 (Red Hat 4.1.0-3):

g++ -g -I /boost_1_33_1/ -std=c++98 -pedantic main.cpp -o car_assembler
main.cpp: In constructor 'default_state<T>::default_state(typename 
boost::statechart::state<default_state<T>, sample_machine<T>,

mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, 
mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, 
has_no_history>::my_context)':
main.cpp:51: error: there are no arguments to 'post_event' that depend on a 
template parameter, so a declaration of 'post_event' must be available
main.cpp:51: error: (if you use '-fpermissive', G++ will accept your code, but 
allowing the use of an undeclared name is deprecated)
make: *** [debug] Error 1

With gcc32 (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-55.fc5):

g++32 -g -I /boost_1_33_1/ -std=c++98 -pedantic main.cpp -o car_assembler
In file included from main.cpp:19:
/boost_1_33_1/boost/statechart/transition.hpp:48: no class template named `

main.cpp:44: object `<expression error>' cannot be used as template argument
