OK, I missed some warnings (red head) which actually tell me that no
dynamic link library will be made. 

[The first warning is repeated for several Boost libraries]

*** Warning: linker path does not have real file for library -lboost_system-mt.

*** Warning: linker path does not have real file for library -lpthread.

*** you link to this library.  But I can only do this if you have a

/usr/lib/gcc/i586-mingw32msvc/4.4.4/../../../../i586-mingw32msvc/lib/libmswsock.a
*** The inter-library dependencies that have been dropped here will be

*** Since this library must not contain undefined symbols,

*** libtool will only create a static version of it.

It seems to be related to

Is the hack that is mentioned necessary or is there another solution?

TIA
