As I said, I'm just following directions from LSF (Linux From Scratch)
http://archive.linuxfromscratch.org/lfs-museum/6.6/LFS-BOOK-6.6-HTML/chapter05/gcc-pass2.html
Everything I've done is based on this and another reference. Combined with
some of my own figuring out how to make it work.

I recently found a reference that shows some threads being win32 rather then
pthreads "--with-libgc-threads=w32" is another option I've seen recently,
and I was wondering if there is also "--with-msvc-threads" I can't seem to
find that exactly though. No there is no need for pthreads accept for just
figuring out the right options right now.

I'll try the flags you are suggesting, would you suggest I do anything
different for Pass 1 of building binutils, and gcc?
I skipped the Linux Headers, and glibc, and just use mingw-64 headers, and
msvc headers.
Also I had to do that before I made gcc pass 1. rather then after. otherwise
gcc doesn't build right without the mingw headers.
Please refer to the LFS book for more reference to what I'm talking about.
If you want I can send you the entire history of commands I have done (in
the order I did them), I write them all down so I can reproduce it if I have
to.
This also includes where I get my sources from.
Thank you for the input and help thus far.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
