Hi, When I try the example from the manual for Autoconf
AC_CHECK_HEADER(elf.h, [AC_DEFINE(SVR4) LIBS="$LIBS -lelf"]) I get a warning from autoheader: $ autoheader autoheader: warning: missing template: SVR4 autoheader: Use AC_DEFINE([SVR4], [], [Description]) Is AC_DEFINE not being used? What is wrong: the manual or the template, or is something else going on? (Autoconf version 2.59). Thanks, Frederik Fouvry
