seems not to work out of the box. since i am new to bjam i would like to 
start with something simpler :)

up to now i live with that "solution" (which is all but readable or good 
scaling

import os ;

if [ os.name ] = NT
{
        # execution of shell-script wx-config is required, thus
        # the script is called in context of sh.exe context.
        # requires that sh.exe is in PATH
        # the first sed changes all / to backslash e.g. c/Programme --> c\Programme
        # the second sed changes all include directives e.g. -I\c\Programme --> 
-Ic:\Programme
        # tr removes the trailing newline
        # note: all escapeing backslashed are required twice (one for bjam and 
one for sh )
        wx_cxxflags = [ SHELL "sh wx-config --cxxflags | sed -e 
's/\\//\\\\\\\\/g' | sed -e 's/-I\\\\\\\\\\(.\\)/-I\\1:/g' | tr -d 
'\\n'" ] ;
        wx_linkflags = [ SHELL "sh wx-config --libs | tr -d '\\n'" ] ;
}
else
{
        # tr removes the trailing newline
        wx_cxxflags = [ SHELL "wx-config --cxxflags | tr -d '\\n'" ] ;
        wx_linkflags = [ SHELL "wx-config --libs | tr -d '\\n'" ] ;
}
