Anybody uses math/slatec?
This is a collection of >1400 f77 routines.
The problem is that there is no upstream anymore,
and the code has deleted features, e.g.:

dplpmn.f:216.72:

20019 ASSIGN 20020 TO NPR007                                            
                                                                        1
Warning: Deleted feature: ASSIGN statement at (1)

dplpmn.f:624.18:

      GO TO NPR005, (20018,20154,20243)                                 
                  1
Warning: Deleted feature: Assigned GOTO statement at (1)

The full log:

Fixing each individual deleted feature is not that hard.
However, there are a lot of those.
In addition, there is a risk of introducing new bugs.
The library, as it is, is supposed to be thoroughly tested.

So I'll asking for opinions on what to do
with math/slatec; (1) nothing - leave as it is,
(2) try updating deleted (and obsolete) language
constructs, (3) spawn another port, with
no deleted or obsolete features, but with little testing?
