I have a working port on cygwin32. My port is based on the snapshot as
of Feb 24. The following description may only work with that snapshot. 
In particular, 1.0b3 is totally different.

(1) First of all, edit config.guess so that it returns i386-pc-cygwin32
								    ^^^^
instead of i386-pc-cygwin32.

(2) There are several places in source at which they think the
directory separator is '\' instead of ':'.  They are:

	include/system.h
	kaffe/kaffeh/support.c

Search 'PATHSEP' and fix them.

(3) I had a trouble with libtool. The configure tries to build shared
library, but make fails when it builds libnative.a.  At the moment, I
simply do this:

	configure --disable-shared ...

-------------------

I hope it works for you. I also welcome an improved info for the above
problem (3). I do not know how things are supposed to work on cygwin.

As a general comment, it is very common that programs written MSWIN32
environments in mind assume that the directory separator is '\'. This
is not correct under cygwin32.
