    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello Matthias,

I will have a look and try to compile yade with QUAD_PRECISION defined
trying to eliminate all errors. Unfortunately currently I am a bit busy, so
probably it won't be finished this week. But should be beginning of the
next week, I will inform you :-)
cheers
Jan
