Unfortunately it doesn't solve my problem. Here is the situation: I run
pcb in gdb and break ps_get_export_options, then draw something and export
to ps. At this point, in the scriptable HID, I nees to know which exporter
the user choosed (ps in this case). Global variable "gui" is set to the
gui hid, so that doesn't help any.

You said the modification I suggested was overkill. Did you mean it would
be too much work, or passing +1 pointer to those functions would slow the
program too much or would add too much bloat? In the first case, I could
prepare a patch. 

If adding the hid pointer to those calls is really that bad, why not
adding a new global variable called "current_exporter" which would be set
in the gui hids, before the first call to the exproter? It would be less
than 16 new lines in the code, I think :)
