Ok, several things happened:
1)
The log entry changed to "Command string for CreateProcessA(): 
'-ftemplate-depth-128  ..."
which I know from earlier experience as indicating an inability of 
boost-build to detect my compiler.
In my user-config.jam it is defined as:

using gcc
     : 4.6.2
     : "C:/subsys/win32/mingw-4.6.2/bin/g++.exe"
     : <flavor>mingw32
       <root>"C:/subsys/win32/mingw-4.6.2/"
       <archiver>"C:/subsys/win32/mingw-4.6.2/bin/ar.exe"
       <rc>"C:/subsys/win32/mingw-4.6.2/bin/windres.exe"
       <cxxflags>-fno-strict-aliasing
       <linkflags>-Wl,--allow-multiple-definition
     ;

And I request this compiler from the cmd line as:
b2 mytarget gcc-4.6.2-mingw32
which worked before, and still works for the 4.7.2 compiler which is 
also in user-config.jam (altough it is the first compiler specified in 
the file, the default compiler)

2)
A second observation is, that I am not able any-more to use 
toolset-add-requirements within the user-config.jam to add requirements 
(well indeed only a specific one) to my compilers
I.e.:

using gcc
     : 4.7.2
     : "C:/subsys/win64/mingw64-4.7.2/bin/g++.exe"
     : <flavor>mingw64
       <root>"C:/subsys/win64/mingw64-4.7.2/"
       <archiver>"C:/subsys/win64/mingw64-4.7.2/bin/ar.exe"
       <rc>"C:/subsys/win64/mingw64-4.7.2/bin/windres.exe"
     ;

toolset.add-requirements
         <toolset-gcc:flavor>mingw64:<target-os>windows
         <toolset-gcc:flavor>mingw64:<architecture>x86
<toolset-gcc:flavor>mingw64:<instruction-set>core2
         <toolset-gcc:flavor>mingw64:<address-model>64
         <toolset-gcc:flavor>mingw64:<threadapi>win32
         ;
Does not add architecture property (which my Jamroot depends on).

I hope you can help.

Thank you, Roland.
