Sam, > checking for getrlimit declaration... (cached) install-shextern int getrlimit > (enum __rlimit_resource, struct rlimit *); In all macros that I wrote, you can replace AC_MSG_RESULT([${ac_t:- }...]) with AC_MSG_RESULT([ ...]) Like it was done in iconv.m4 <http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=c9656c46525e79547e2ffe10130e0e8e013e169c> > 1. optional: what is the history of the matter? In older versions of autoconf, ac_t was set to newline + 9 spaces. Later it was undefined. Now it got the value 'install-sh' in some cases. > 2. required: is there a replacement for ac_t or should it be dropped? It can be dropped, and a hardcoded value can be used instead. The newline + 9 spaces should lead to this output: checking for getrlimit declaration... (cached) extern int getrlimit (enum __rlimit_resource, struct rlimit *); Bruno _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
