[Boost-build] cygwin - mingw confusion

I've got separate cygwin and mingw installations of g++ on my machine.

user-config.jam includes these lines:

using gcc : 4.3 : g++-4 : <cxxflags>"-std=gnu++0x -Wl,--enable-auto-import" ;
using gcc : 4.4 : c:/gcc/bin/g++ : <cxxflags>"-std=gnu++0x
-Wl,--enable-auto-import" ;

If the second line is commented out, bjam --toolset=gcc-4.3 works as expected.

But if the second line is not commented out, bjam --toolset=gcc-4.3 thinks
it isrunning under mingw. See below.

Is this a bug or a feature:-?
