[C++-sig] Problem Crosscompiling boost python modules

[Simon Norberg]

I have continued trying to crosscompile boost python modules, and i 
found something that i cant understand why it results in errors.
lets begin with:
http://pastebin.com/f569662b8
it corsscompiles perfectly with:
i586-mingw32msvc-g++ hello.cpp -shared -o hello.pyd 
-I/usr/local/i586-mingw32/include/soci/ 
-I/usr/local/i586-mingw32/include/soci/sqlite3/ 
-I/usr/local/i586-mingw32/include -I /usr/local/i586-mingw32/include/ -I 
/usr/local/i586-mingw32/include/python/ -I 
/usr/i586-mingw32msvc/include/ -L/usr/local/i586-mingw32//lib  
/usr/local/i586-mingw32/lib/libsoci_core-gcc-2_2.a 
/usr/local/i586-mingw32/lib/libsoci_sqlite3-gcc-2_2.a 
/usr/local/i586-mingw32/lib/libsqlite3.a 
/usr/local/i586-mingw32/lib/libpython25.a 
/usr/local/i586-mingw32/lib/boost_python-mgw.a

butt if i add this 2 lines to the beginning of the file:
#include "soci.h"
#include "soci-sqlite3.h"

and compile with exactly the same options i get:

And then i don't even use anything at all from those libraries, and the 
error are not related to those libraries either as far as i can tell.
