I thought that in my example Makefile.am I had correctly ordered CFLAGS
and JITTER_CFLAGS so that JITTER_CFLAGS takes precedence in case of
contradictions, and any optimisation option different from what is
required is automatically undone.

That part of the design is not recent, and I only have a vague
recollection of it now.  I remember being pleasantly surprised by the
fact that such a solution in fact existed.  I may have discussed about
this with you or with some other friend, maybe Alfred.

Anyway a reliable solution is simple: compiling vm2.c (and only that:
the rest is not critical) with JITTER_CFLAGS *only*.


No, no-threading code can not be compiled without optimisation.  It is a
matter of correctness, not performance.  The same holds for
minimal-threading.
