I have just tried this on a local Alpha running OSF1 V3.2 and there
was no problem.  I used the native C compiler and needed to have a
special flag set to get the beast to generate code for IEEE.  Perhaps
something similar is needed for gcc.

Could you refresh my memory on this please.  I have forgotten
what the problem was.

I don't think that I made any changes in the nlm or glm code, but I
will take a look.  Can you send me a simple example which trips the
problem.

Could you send me the output from etc/config.guess on the alpha.
I may be able to find a similar local machine to test on.
