Ah, I realized my mistake, and, predictably, it was a matter of not
reading the instructions well enough.
"NOTE: For v3 (trunk as of writing, you MUST append x86_64-w64-mingw32
to your prefix, such as --prefix=/mypath/x86_64-w64-mingw32 NOTE: You
MUST also do this for the HEADERS "
I assumed this didn't apply if I wasn't using a custom prefix, but I can
see I was mistaken.
Thanks for putting up with my novice questions.

Something is very wrong if the mingw headers for your cross compiler
are installed directly in /usr/local/include on your Linux machine.
Since those headers don't apply to software compiled for your Linux
machine, they should be in a directory named something like
i386-w64-mingw32.
Now look at the error you posted. I'm not sure what program you were
trying to configure, but clearly it is wrong to try to use "gcc"
(which would be your Linux machine's native GCC, used to build Linux
programs) with the MinGW headers (which are meant for native Windows
software). That's why _mingw.h is complaining: you're trying to use
it with the wrong compiler.
If you're interested in cross-compiling from Linux to Windows, you
might want to look at my Nixcrpkgs project, since I've already figured
out a lot of the basic issues and you can reproduce my results
reliably by just running a few commands:

Hello,
I am interested in implementing, or helping to implement, support for 16-bit
code and NE executables in mingw.
I am trying to build the gcc cross-compiler (i386-w64-mingw32-gcc) in
accordance with the instructions at
https://sourceforge.net/p/mingw-w64/wiki2/Cross%20Win32%20and%20Win64%20compiler/
but I run into an error configuring gcc:
configure:5564: checking for the correct version of gmp.h
configure:5584: gcc -c -g -O2 conftest.c >&5
In file included from /usr/local/include/crtdefs.h:10:0,
from /usr/local/include/limits.h:6,
from /usr/include/gmp.h:56,
from conftest.c:10:
/usr/local/include/_mingw.h:264:2: error: #error Only Win32 target is
supported!
I built binutils and the headers for multilib, so I do not understand why I
am encountering this error. Can anyone help with this problem?
Thanks,
Zeb
