there is a problem with the common fixup system -- I think Andrei 
implemented it.

K functions expect a pointer to pv_spec_t and now a pv_spec_t** is 
returned when fixup_pvar() is used. fparam_t.v.pvs is a pv_spec_t* and 
the *param (from fixup call) is filled with &fparam_t.v.

A solution would be to add a void *fixed_param to fparam_t that is 
either set to &fparam_t.v or to a filed insind 'u' union, and this one 
is used to fill the 'param'.

Cheers,
Daniel
