Hello,

I am sorry, but I think that I solved the issue by running a make clean
Now the generated code is the same on both machines.

Probably I have an object from a previous version of gsl which was not recompiled
at the same time on both machines.

My Makefile is probably not optimum.

How can I force a compilation in case of an update of a library like gsl?

I think this is a limitation of make. New versions of libraries don't normally

trigger recompiles. I habituall run `make clean` after any significant changes

to external packages.

Thank to every body for the help.

Glad you found a solution. I've had some projects run into big trouble after

linux updates when we couldn't reproduce previous results -- causes have

ranged from bugs in the old library, new bugs in new library, and hardware

failures.
