Let me quote you from the Emacs binary used to report the error that started this thread: system-configuration-options is a variable defined in `C source code'. Its value is "--with-gcc (4.3) --no-opt --cflags -DENABLE_CHECKING=3D1 -DSITELOAD_PURESIZE_EXTRA=3D200000 -DXASSERTS=3D1 -IC:/emacs/build/include -fno-crossjumping" Juanma
