Hello,John,and everybody,

I am sorry to inform you that I could not succeed to configure GCC4.4.0 to 
install h8300 toolchain.
I omitted TARGET_MODE define sentence,and converted GCC4.4.0 source as I 
previously said.

I succeeded binutils configure.
But when I configured gcc, next error happened.

Here are 501-503 lines of libgcc2.c.
#ifdef L_bswapdi2
DItype
__bswapdi2 (DItype u)

Error is caused by not understanding DItype.
Since when I retrieved original gcc4.4.0 sources then not occurred above 
error,
so I am sure I wrongly converted gcc4.4.0 four files.

I am very sorry to bother you,but I do not understand.
I append original and after-converted four files in compressed form.

I appended gcc3.3.2 original h8300.h,t-h8300.
patch-sources/gcc3.3.2-before-patch-sources/h8300.h,t-h8300

And after-patch-applied gcc3.3.2 four files.
patch-sources/gcc3.3.2-after-patch-sources/h8300.h,t-h8300,extfloatlib.c,float-h8300.h

And gcc4.4.0 original h8300.h,t-h8300.
patch-sources\gcc4.4.0-original-sources/h8300.h,t-h8300

And after-converted gcc4.4.0 four files according to patch.
patch-sources/gcc4.4.0-patch-converted-sources/h8300.h,t-h8300,extfloatlib.c,float-h8300.h

I beseech you to look up wrongfully converted codes in after-converted 
gcc4.4.0 four files.

Would you please let me know the error-causing codes.
I am very much obliged.
