Yes, I used the new combined MSYS+MinGW distribution.  The compiler is gcc 4.7.0.  (The infamously bad 386 code was produced by gcc 4.4 and earlier.)

I removed a -mpentium that is not understood by the current compiler.  Finding the right -m switch(es) might be all that's needed to restore the lost performance.
