Build Error -1073740940

Hi all,

I try to build trunk on Windows 7 32-bit.

The last lines of the build output are:
mkdir -p 
C:/LO_buildDebug/core/instdir/share/config/soffice.cfg/writerperfect/ui/
mkdir -p

Makefile:250: recipe for target 'build' failed
make: *** [build] Error -1073740940

I have used
/cygdrive/c/LO_buildDebug/core/autogen.sh \
--with-external-tar=/cygdrive/c/LO_buildDebug/externalsrc \
--with-junit=/cygdrive/c/LO_buildDebug/junit-4.10.jar \
--with-ant-home=/cygdrive/c/cygwin/ant195 \
--enable-pch \
--disable-ccache \
--enable-dbgutil \
--enable-verbose \
--without-fonts \
--with-help

Any idea what goes wrong?

Kind regards
Regina
