Build warning in pyuno

[Mat M]

Hello

I don't know how to fix this, but with cygwin on Win7-x64, I have the  
following warning when starting tail_build:

gbuild module /cygdrive/d/src/libo/tail_build: /opt/lo/bin/make -f  
Makefile -j4 -rs all slowcheck
/cygdrive/d/src/libo/pyuno/Library_pyuno.mk:27: warning: overriding recipe  
for target `D:/src/libo/workdir/wntmsci13.pro/LinkTarget/Library/pyuno.pyd'
/cygdrive/d/src/libo/pyuno/Library_pyuno.mk:27: warning: ignoring old  
recipe for target  
`D:/src/libo/workdir/wntmsci13.pro/LinkTarget/Library/pyuno.pyd'

I am not sure if it is meaningful neither...

Regards
