On a different, but related topic, xorg wiki documented lowest
common denominator for libtool is v1.5. This is pretty old and reported
as buggy. In real life, I speculate that v2.2 is used by all but a very
few systems.

I accidentally discovered that when you create an m4 directory in a
module,
libtool 2.2 copies its macros in there and this is shipped in the
tarball.
When a tarball is built on a system at v1.5, it effectively uses v2.2
anyway.

If all this is correct, I could not see any reason not to declare v2.2
our
minimum version. Using LT_INIT rather than AC_PROG_LIBTOOL would ensure
v2.2 is used which would gives us the assurance that all tarballs are
created
at v2.2 rather than a (possible) mix bag of v1.5 and v2.2.

Thanks
