How would this help? It's not the date of the latest gnulib-tool invocation that matters. Nor is it the date of the latest modified file in the gnulib checkout. But rather the collection of the revisions of all checked-out files. I.e. the 'git' tree serial number. Therefore would it help if gnulib-tool copies the contents of $gnulibdir/.git/refs/heads/master into the generated gnulib-cache.m4? Bruno
