In my adventures with tools/dev/unix-build/Makefile.svn, I saw two places that call '-which', that is, 'which' preceded by a dash.
One of these is in the recipe for gettext's configure. It was changed from 'which' to '-which' in r1577186. I'm not familiar with this. What does '-which' do, and how is it different from 'which'? Thanks, Nathan
