Sorry, I probably missed that mails.
Yes I'm using CVS-HEAD.
Thanks for the hint. I was a bit wired about the problems and searching for
problems on the host-side.

This sounds familiar. Developing GUI / multithreaded programs, I add a getline
or something similar to the beginnig - just to attach the debugger.
But doing that for configure - no, I have no idea, how to figure that out.
When configure failed telling that it could not determine the size of long
double, it said, more details could be found in config.log - but the end of
the logfile looked like the beginning of a c-header-file. - So I had to guess
That's not really satisfying.
I stil presume, that I am the bug - but that's not easier to debug :(
Anyway - thanks for your hints.
