new gcc and binutils RPMS was Re: Problems with arm-rtems-gcc

[wangyf(sina)]

Thank you very much!
I have downloaded the RPMs and used gcc 2.95.3 to build my programs.
To my surprised, when I use "make", the final BIN file will be about 300K bytes large, but when I use "make CFLAGS+='-fpack-struct' ", the final BIN file will be about 800K bytes large. 
So if I use '-fpack-struct', will gcc disable other optimization?
Thanks!

Best regards,
yunfei

If I type " arm-rtems-gcc ... -fpack-struct ... ", there is no error happening, but the structures in my program will not be packed.
