Ah, gcc.jam detected that you're using mignw version, automatically.
You might want to just try:

        using gcc : : "C:/Compilers/msys/1.0/bin/g++.exe" ;

(not that is has any changes on behaviour)

I never saw this happening before. What's the output of "bjam --version"
and what's the *exact* user-config.jam (just attach it to email).
