Hello,

I am very sorry to have found previous mail was badly formatted.
I send the same text.

I found next patch in GCC project site.

Subject: [patch] conditionally declare bswap functions depending on target

Do you think it is effective ?

I tried to patch to GCC4.4.0 libgcc2.h then resulted in next message and did 
not
change file at all.

$ patch -p0 < libgcc2_h_diff.txt

Apply anyway? [n]
Skipping patch.
1 out of 1 hunk ignored -- saving rejects to file libgcc2.h.rej

I am not deft of handling patch file,so would you please modify it to apply 
to GCC4.4.0 libgcc2.h ?
And please teach me how to apply it.

I append GCC4.4.0 libgcc2.h and patch file.
