Ok, the long lines are not present in any of the Makefile.am's but it is 
present in a Makefile.in.
So, it looks like it is a Automake generated line.

Ok, fine with that.

Since we use gmake on all platforms for a long time we did not run into that 
part.

Definitly, as we talk about that, it gets clear that automake might be the 
offending part.

So I will ask at address@hidden

   Thanks!
