I don't know if that improves your experience or not.

If you want to make the logs easier to decypher, drop the -j4 for the make command - it makes logs easier to parse.

I can see some unix essential commands like diff are not found - make sure your cygwin installation is complete for development. (diff, bison, flex)

This seems to be the actual error:

configure: error: in `/home/JMan/binutils-build-2.23.1/ld':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

config.log might've been turned into the mess by -j4 as well, so I'd re-run with make -j1 and then inspected the config.log file for the actual error. Then Google.

Yes the whole thing is complete from start to finish.

I was actually talking about the boot up asm file.

And everything without section is now probably missing from your final binary.

mov eax, 0xdeadbeef
int 33

test.o:	file format ELF32-i386

Contents of section :
Contents of section .text:
 0000 b8efbead decd21                      ......!

A few of the gcc tests are also failing for conftest, which I believe ties into m4 as well. Try installing that package and see if it fixes the problem, otherwise post current config.log after doing that. Hope this helps.

I started with djgpp and then used cygwin on win 7 64 bit for quite a while with my own crosscompiler and never had any of your issues. Before I created my own crosscompiler in cgywin, I solved the pe non file format error by assembling to coff and then compiling gcc as pe/bin and converting the file format to elf using objcopy. It solved the issue but generated a larger binary so I would have to strip sections from the binary to get it smaller. Always seemed like a hack but worked perfect, was much easier to compile code once I switched to a crosscompiler.

Switched to linux and haven't looked back. If I have some time today, I'll test your code and see what issues I have on my win 7 64bit machine. The last version of gcc on cygwin I used was 4.7.x so will have to update my tools when I get home from work.

Somehow it tries to use /lib/cpp as the preprocessor. I don't know why, or which system confiruation setting is wrong.

(Also I noted you have copied --program-prefix configure option wrong - it should equal $TARGET- instead of just $TARGET, otherwise you'd get program names like i586-elfld instead of i586-elf-ld)

Serves me for still believing one has to avoid the issues that existed five years ago.

It's still good manners to do it properly, if anything.

global start
extern main

[BITS 32]
start:
call main

cli

EXTERN code, bss, end

mboot:
   dd mboot
   dd code

   dd start

In Cygwin's installer, you need to separately select the gcc4-core and gcc4-g++ packages for proper configuration of the host compiler.
