Hi Svenn,

What backend are you using, vhdl or vams?

If vhdl, the only change needed is to change
vhdl:write-context-clause e.g. as follows:

(define (vhdl:write-context-clause)
  (let ((prolog (gnetlist:get-toplevel-attribute "vhdl-prolog")))
    (format #t
            (if (string=? prolog "not found")
                "-- Context clause
library IEEE
use IEEE.Std_Logic_1164.all;
"
                prolog))))

The same could be done for vams. If this works for you, I could
commit such changes. The only thing we have to discuss before is
the prolog attribute name conventions.

Of course, you might your own backend for personal use. However,
if such a change is useful for you and harmless for others, why to
not have it?
