No it was me not reading your message properly! I realised just after
I replied what you meant.

As far as I can tell the rest of the "long double" type functions 
seem to be ok, it was just the ceill one that was "misbehaving".
I did have some trouble with sqrtl a while ago, but I don't think
the problem was related to this.

Thanks for the help Gwenole, it's *much* appreciated.

John.
