Re: Strange MXCSR messages?

    Ok, it should now be fixed.  I removed the fnsave/fxsave instructions
    from libc_r entirely... fxsave can't be used there anyway because
    the FP state on the signal stack is not 16-byte aligned (it was causing
    an infinite loop, which is another issue but one I'm not going to worry
    about right now).

    Now the kernel is 100% responsible for saving and restoring the FP state.

    Now that its fixed, I also changed the kernel to SIGFPE a user
    program that messes up the MXCSR.
