Thanks for the offer and sample code.  However, no, we are not looking
for a new build system.

Meson has heavy build requirements (python3 and ninja are listed), and
this may not work for FreeBSD base system.  We already avoid build
dependencies on gmake, and gcc.

Otherwise, the autoconf system neatly fits onto package managers'
systems and expectations.  We also worry about all built details for
compromises and portability fixes that we had accrued so far that would
be lost.  We appreciate a build system that may be better, but are
invested in the legacy system for now...

Best regards, Wouter
