Compiling Emacs 23.1.92 on Windows fails

[Christoph]

Hi,

I have been trying to compile Emacs Pretest 23.1.92 on Windows 7 (cygwin, MinGW, GnuWin32) but haven't had any luck.
 
I run

configure.bat --no-debug --with-gcc --without-png -cflags -IC:\Progra~2\GnuWin32\include

then

make bootstrap

and everything runs fine until I get this error:

[...]

Any idea what is causing this?

Thanks,
