The general approach is insert the ChangeLog, as text, in the body of
the email message.  Create a patch for the actual changes to the
source code and append it in the message if it is small or attach it
if it is large.

I have added your patch, but LDFLAGS only includes -static-libstdc++
-static-libgcc for stage1, when the initial GCC does not implement it.
I configure with

--with-boot-ldflags=-L/usr/gnu/lib

so that bootstrap will find the gmp, mpfr, mpc shared libraries.

Do you have those libraries built statically or shared?

Thanks, David
