I've been building with autoconf 2.5. However, after the 1st make, I've had
to force a "clean" by ...
$ hg status | grep '^? ' | sed "s/^? /rm /g" | /bin/sh
If I did not do that, I'd encounter errors for unresolved dependencies.
I'm now building with autoconf 2.6.
I'm unfamiliar with autotools, but I took a peek at configure.ac and don't
see a check for the version of autoconf.
I noticed the comment below in acinclude.m4
25 dnl If needed, define the m4_ifblank and m4_ifnblank macros from
autoconf 2.64
26 dnl This allows us to run with earlier Autoconfs as well.
27 dnl FIXME: these should go away once Autoconf 2.64 is required or
ubiquitous.
Is the version of autoconf checked anywhere? If not would it make sense to
add a check to autogen.sh? .. or should acinclude.m4 be modified to require
autoconf > 2.64?
