Comment(by Severin Kacianka <severin@…>):

 sorry for my late reply, but i was very busy this week.

 I think you are right. However how do I compile boost with -fshort-enums
 or check that it compiled with it? Here is what a tried:
 {{{
 $ bjam cxxflags=-fshort-enums --prefix=/home/severin/software/boost_test
 install
 ... boost compiles ....
 $ g++ -L/home/severin/software/boost_test/lib/
 -Wl,-R/home/severin/software/boost_test/lib/
 -I/home/severin/software/boost_test/include/ test.cpp
 -lboost_program_options -fshort-enums
 $ ldd a.out
         linux-gate.so.1 =>  (0xffffe000)
         libboost_program_options.so.1.42.0 =>
 /home/severin/software/boost_test/lib/libboost_program_options.so.1.42.0
 (0xb7fbc000)
 (... other libs ...)
 $ ./a.out
 Segmentation fault
 }}}
