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=1
-DSITELOAD_PURESIZE_EXTRA=200000 -DXASSERTS=1 -IC:/emacs/build/include
