 After twelve hours two of them are converted to GO (Guile Output?) files,
 a third one (language/cps/intmap.scm) is in the works:

 {{{
 -rw-r--r-- 1 macports admin 104389  3. Sep 02:11 ice-9/eval.go
 (≈4h)
 -rw-r--r-- 1 macports admin 679597  3. Sep 10:38 ice-9/psyntax-pp.go
 (≈8h)
 }}}

 (Arithmetically the build will have finished around the ides of September.
 At reduced, minimal setting, CPU speed to keep the PowerBook G4 real
 silent.)
