I am trying to build wine-4.15 and get messages like this
------------[ build log snippet ]------------
/usr/gcc/6/bin/gcc -c -o xslpattern.yy.o xslpattern.yy.c -I. \

I see that the patch needs more work as there are other places (e.g.
dlls/msxml3/xslpattern.l) where I get 'redefined' messages too.

Thanks,
Evgeny.
