Thank you for the suggestion!
This indeed changed the behaviour, now the build stops after having done 
the configuration steps, just before starting to compile.
In my stage directory I can find a config.log file with content:

----
...found 16 targets...
...updating 9 targets...
common.mkdir build\bb\boost
common.mkdir build\bb\boost\bin.v2
common.mkdir build\bb\boost\bin.v2\libs
common.mkdir build\bb\boost\bin.v2\libs\regex
common.mkdir build\bb\boost\bin.v2\libs\regex\build
common.mkdir build\bb\boost\bin.v2\libs\regex\build\gcc-mngw6-4.6.2
common.mkdir build\bb\boost\bin.v2\libs\regex\build\gcc-mngw6-4.6.2\dbg
CreateProcessA() Windows API failed: 2 - Das System kann die angegebene 
Datei nicht finden.
----
The last message is partly german, meaning that the "System cannot find 
the given file."
But no hint which file. Starting b2 with --verbose doesn't help either, 
nor does --debug-configuration.
The command line I am using to invoke b2:
 >b2 my_target gcc-4.6.2-mingw32
Subversion revision id is:  989
The Subversion message is from my Jamroot, a call to svnversion to read 
the svn number from my tree.
The very same runs without any issues with the 1.53 version that came 
with boost.
I am glad about any hints you can give me. Is there a document of 
changes I should look into? Are there any new environment variables 
beyond BOOST_BUILD_PATH I need to take of in the latest version?
