[Help-gsl] set_error_handler_off() at compile

[Altro]

Hi,

I wish to know if there is way to use something along the lines of 
`gsl_set_error_handler_off()` as in here: 
https://www.gnu.org/software/gsl/manual/html_node/Error-Reporting-Examples.html, 
but at compile time (for example writing a preprocessor macro).

The reason for it is that I'm writing a function to be called by python, 
so I don't have a `main()` I wish to avoid the `abort` when an error occurs.

Many thanks to all the community for developing and supporting such good 
libraries.
