Pretty much everything as far as I can tell.

Having added as.exe, ld.exe to the Emacs bin directory, and having
updated PATH and exec-path to include this directory (from inside Emacs
-- whether this is the long terms solution at the moment, I do not
care yet), I get this error.

I have checked the library paths as well as I know how (gcc
--print-search-dirs). I have reformatted the output with some new lines
to make it readable.

The equivalent version for an Emacs run from mingw64 shell (which works
and JIT compiles), I get this.
