relative time modifiers in getdate yacc parser broken with coreutils 5.94

[Andreas Arens]

Symptom:
the 'ago' keyword only applies to the last descriptive time element, not 
globally as it did before.

Sample:
(coreutils 5.3.0 - correct)
date -d '5 hours 30 mins ago'
Thu Apr 20 14:18:52 CEST 2006
date -d '5 hours ago'
Thu Apr 20 14:48:56 CEST 2006

(coreutils 5.94 - wrong)
coreutils-5.94/src/date -d '5 hours 30 mins ago'
Fri Apr 21 00:21:05 CEST 2006
coreutils-5.94/src/date -d '5 hours ago'
Thu Apr 20 14:51:10 CEST 2006
coreutils-5.94/src/date -d '5 hours ago 30 mins ago'
Thu Apr 20 14:21:17 CEST 2006

The 3rd example is nonsense, as the parser is intended to interpret natural 
speech, but shows the problem.

Please CC me on a solution, I'm not subscribed.
