Please keep replies on list, so that others may see them in the archives,
and so that you are more likely to get a decent response.  I am not the
official m4 maintainer, only an interested party since I maintain the
cygwin distribution of m4.  The maintainer, Gary Vaughn, is currently
occupied with putting finishing touches on libtool 2.0 at the moment.

According to Mikhail Teterin on 12/17/2005 12:11 PM:

Then YOU try convincing the glibc maintainers to fold in all the gnulib
regexp patches (it's a tough job, as Paul Eggert already found out).

m4 2.0 depends on dynamic modules.  Not all platforms support dlopen(),
and even those that do have different semantics.  Libtool is absolutely
essential to getting sane behavior of dynamic modules across as many
platforms as the current m4 1.4 targets; without libtool support, it would
be impossible to just put out a README of how to compile.  But you are
welcome to check out the m4 CVS repository and build it yourself to see
what will be available when m4 2.0 is finally released; note that CVS m4
currently requires CVS libtool, autoconf, and automake.
