[Cygwin] [Master] failure when compiling liblangtag

Hello

it was already like that yesterday, and to day too, with commit  
7f101a29e12ce6ca

After a failure of a "standard make", I did:
make liblangtag.clean && make verbose=t liblangtag
which told me
cd D:/src/libo/liblangtag && /opt/lo/bin/make -j 4 -rsr clean

And here is the end of the log
