I have managed to build the latest snapshot more or less OK with the Cygwin.
I used a configure line similar to this except I used an older m68k-coff
toolset(one thing at a time ;) and the efi332 BSP. It worked more or less OK
apart from:

 - The initial configure chokes when it trys to configure the tools. I
complains about not being able to build executables with the gcc installed
on the system. You can fix this by setting CC=gcc before configuring...but
this seems a hack. Has anyone seen this behaviour or is it just my setup?

 - The good old NTVDM error dialog keeps coming up during the make at each
check for the cross-compiler. Just hitting "Terminate" fixes this.
Cygwinb1.dll needs hacked so it does some sort of check that the EXE it is
trying to run is a PE, NE or DOS EXE before going on to call NT's Create
Process (which thinks that anything that isn't in this category is a ye olde
.COM and can just be loaded and run)(a behaviour I would really like to see
turned off in NT - although it fails gracefully when presented with garbage,
unlike Win9x).

The build does take a *LOT* longer than it used to though due to all the
extra configure steps which have a real performance hit on Beta 20.1 :(

Other than that it works fine.

My Cygwin setup is pretty clean. Cywin Beta 20.1 with cygwin Perl installed
to /usr/local/, latest versions of autoconf and automake and the following
config files:

j:\cygnus\cygwin-b20\cygnus.bat:
@ECHO OFF
SET MAKE_MODE=UNIX
SET PATH=J:\cygnus\cygwin-b20\H-i586-cygwin32\bin;%PATH%
SET CYGWIN=binmode
SET HOME=/home
bash

~/.bashrc:
export
PATH=/cygnus/cygwin-b20/H-i586-cygwin32/bin:/gcc-m68k/bin:/usr/local/bin

and a pretty boring binary mount table:
bash-2.02$ mount
Device           Directory           Type        Flags
\\.\tape1:       /dev/st1            native      text!=binary
\\.\tape0:       /dev/st0            native      text!=binary
\\.\b:           /dev/fd1            native      text!=binary
\\.\a:           /dev/fd0            native      text!=binary
j:\cygnus        /cygnus             native      text=binary
f:\gnu-unix\archive /archive            native      text=binary
j:\gnu-unix      /                   native      text=binary
bash-2.02$

hope this helps,
Dave
