Hello,John,and everybody,

Thank you John for your reply.
I think I became a little bit knowledgeable.

First I tried to use GCC 4.3.2 for installing h8300 ToolChain.
But it resulted Segmentation error at configureration.

I asked to gcc mailing list but could not get reply.
I tried to use GCC 4.4.0 and there was no error,so I am determined to use 
GCC 4.4.0.

I downloaded the patch file but it is for use of GCC 3.3 source.
I also get the same purpose patch file that is for GCC 3.3.2 source.
I append it in zip file.

I studied it and learned that I could not use it for GCC 4.4.0 source per 
se.
I searched Internet for newer patch corresponding to GCC 4.4.0 or at least 
to GCC 4.3.2 but could not find one.
Couldn't it be possible that you send me the newer patch corresponding to 
GCC 4.4.0 or at least to GCC 4.3.2 ?

If I could not get it I must study the old patch and change the GCC 4.4.0 
source manually.
It is hard, isn't it, because there are too differences between GCC 3.3.2 
and GCC 4.4.0.

Do you have any better idea ?
