AC_DEFINE problem

[Frederik Fouvry]

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
