Hmmm. m4/getdate.m4 does AC_REQUIRE([gl_BISON]), but m4/bison.m4 DOES blindly use 'bison -y' rather than 'missing bison -y'. Maybe bison.m4 should be updated to better check for a new enough bison, perhaps building on autoconf's AC_PROG_YACC or AC_PATH_PROG.
maybe a bug report to gmane.comp.parsers.bison.bugs should be created ?
sure I understand; in fact it was not a great problem after all (an apt-get install bison solved it nicely); I reported it just to let you know...As for building coreutils, if you pick up a distribution such as 5.93, bison should not be necessary (GNU coding standards require that source distributions include the pre-compiled getdate.c along with the source getdate.y); in a distro, bison is only needed if you touch getdate.y. But when building from CVS, projects are free to assume that you have more development tools on hand, such as a new enough bison; because CVS does not include generated tools when the developer can be reasonable expected to regenerate the files himself.
