I've seen that 2.4.4 is coming up so I've decided to take a look at this.

I'm not sure about undefining _WIN32.  I think it is still win 32
environment but more "unix/posix" like.  Unfortunately I don't have enough
knowledge of cygwin to tell what is the best way :).  The other problem is
that I don't know how to turn it off in an elegant way :))).  Probably
adding -mno-win32 to CFLAGS should help since in 
../gcc-lib/i686-pc-cygwin/3.3.3/specs there's something like:

*cpp:
%(cpp_cpu) %{posix:-D_POSIX_SOURCE}   %{mno-win32:%{mno-cygwin: %emno-cygwin
and mno-win32
 are not compatible}}   %{mno-cygwin:-D__MSVCRT__ -D__MINGW32__
%{!ansi:%{mthreads:-D_MT}}
}  %{!mno-cygwin:-D__CYGWIN32__ -D__CYGWIN__ %{!ansi:-Dunix} -D__unix__
-D__unix }  %{mwin
32|mno-cygwin:-DWIN32 -D_WIN32 -D__WIN32 -D__WIN32__ %{!ansi:-DWINNT}} 
%{!nostdinc:%{!mno
-win32|mno-cygwin:-idirafter ../include/w32api%s -idirafter
./../include/w32api%s}}

I can't find the description of this in the info files.  But doing this
gives me the following:

I don't know why HAVE_WINDOWS_H is defined in the result of running
configure - the error comes from search.h lines:

#ifdef HAVE_WINDOWS_H
#include <windows.h>
#endif

while configure with the -mno-win32 gives me:

checking windows.h usability... no
checking windows.h presence... yes
configure: WARNING: windows.h: present but cannot be compiled
configure: WARNING: windows.h:     check for missing prerequisite headers?
configure: WARNING: windows.h: see the Autoconf documentation
configure: WARNING: windows.h:     section "Present But Cannot Be Compiled"
configure: WARNING: windows.h: proceeding with the preprocessor's result
configure: WARNING: windows.h: in the future, the compiler will take precedence
configure: WARNING:     ## ------------------------------------------ ##
configure: WARNING:     ## Report this to the AC_PACKAGE_NAME lists.  ##
configure: WARNING:     ## ------------------------------------------ ##
checking for windows.h... yes

IMHO if the windows.h is not usable we should not define HAVE_WINDOWS_H (see
also PS note)

For sure the attached patch works FOR ME :), at least it passes 'make check' 
and does not show the problematic behaviour.  Do not apply it blindly :)),
although I modified only some #if.. _WIN32 directives I'm not sure whether
all of them are needed/correct (e.g. it looks like geteuid are defined but
I don't know what is their semantics, symlinks are emulated by the cygwin
and I don't know if this kind of support is enough for swish-e - I had no
problems with this so far).

Best regards
Andrzej

BTW. I've just checked that the defaults are
aao014@aao014-01 ~/tmp
$ cat test.c
#ifdef _WIN32
"Aqq na muniu"
#endif
aao014@aao014-01 ~/tmp
$ gcc -E test.c
# 1 "test.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "test.c"
aao014@aao014-01 ~/tmp
$ gcc -E -mwin32 test.c
# 1 "test.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "test.c"

"Aqq na muniu"

so I need to tell explicitely to preprocessor that I wan't _WIN32 to be 
defined.  I don't understand autoconf/automake enough to try to figure out
why it is defined during swish-e build.
