Hm, I do not understand this. Maybe you could give more details? Could
you send me a copy of the "linup-1.c" file produced by McStas with this
problem?

I tried to log in on my account on your host "lnsa15.psi.ch" and run the
linup-1 example. The version of McStas installed on this machine appears
to be v1.0, and I could compile and run the linup-1 example without
problems. I also had no problems with my private installation of McStas
v1.1 on this machine.

Yes, this is a known problem/feature of the Digital Unix C compiler. I
just added an explanation of this problem to a new "FAQ" with this
address:

    http://neutron.risoe.dk/mcstas/FAQ.html

Basically, it is necessary to pass the "-std1" option to the Digital C
compiler to get ANSI C semantics, like this:

    cc -std1 -o linup-1 linup-1.c -lm
