     If this is the usage then it seems to me that you only need a
     unique code for the errors you want to special-case this way.
     You can use a generic code for other errors.
     
     How often do you want to special-case errors this way?  What
     situations have come up so far?

So far, only one.  I suppose we could have errors default to a
PSPP_GENERIC_ERROR value, and have particular values for the ones I
want to catch.  I don't know if this would cause problems with psppire
interacting with other esoteric gnome applications; I'll have to ask
someone who knows about such things.
