demo-i686.sh for building kernel 2.6.30.1

["Zvi Vered" <veredz72 at gmail dot com>]

Hello,

I used demo-i686.sh to build a toolchain for a target based on Pentium-M 
CPU.
The toolchain was built with no errors.

Then I tried to use this toolchain to build linux 2.6.30.1 downloaded from 
kernel.org with:
make ARCH=x86 CROSS_COMPILE=i686-unknown-linux-gnu-

I got an error message:
lx10010218:a99059(linux-2.6.30.1)>make ARCH=x86 
CROSS_COMPILE=i686-unknown-linux-gnu-

include/linux/compiler-gcc4.h:8:4: error: #error Your version of gcc 
miscompiles the __weak directive
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2

According to include/linux/compiler-gcc4.h I should use a gcc version higher 
than 4.1.0

I used gcc 4.1.2 instead of 4.1.0 in the crosstool script and built. Then I 
rebuild the kernel. It worked fine.
I also tried to build 2.6.18.8 with 4.1.0 and it worked. Somewhere between 
2.6.15.4 to 2.6.30.1 the minimum minor version of
gcc was changed from 1 to 2.

Can you update the crosstool script ?

Thanks.
