Thanks for mentioning that. The gnulib bug has nothing to do with 
whether grep works (it's merely a maintainer-tool issue), so I removed 
it from the list of tests for 'grep' by installing the attached patch, 
and am closing the grep bug report. Someone who likes to deal with test 
cases and Perl (probably not me :-) can take a look at it from the 
gnulib point of view whenever they have the time.
