I think this points to something that should be considered for
future Ocaml development, that being a comprehensive test suite
to check the language.  This would also help test porting of the
language to new OSes.

All of the major compilers I can think of, Perl, Python, GCC, etc,
have a test suite and I think from a company's point of view looking
to use the language, a test suite written in Caml would give additional
credibility and a sense of professionalism that would only help
adoption rates.

A good model for the test suite would be Perl's test suite which checks
every aspect of the language and its modules and is written in Perl

Is there any interest in this?
