Rather than open-coding the shell if, why not use: AS_IF([_AM_COND_VALUE_$1], [m4_n([$2])[]dnl m4_ifval([$3], [_AM_COND_ELSE([$1])], [body of else]) which (should) take care of an empty else for you as well, if AS_IF is up to par (and if not, report that on the autoconf list). -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
