Thanks.

I didn't really think about applications refusing to run, but I thought
about people who download pre-built binaries and want to know what's
inside. Some do want ASM, some do not want ASM. They might decide they
have to keep searching the net, or rebuild the binary by themselves; in
the case of Windows and MASM/TASM, that is *if* they have bought the
assembler.

Furthermore, if a (possibly not so obvious) ASM problem occurs and
becomes well-known, bad binaries can be immediately isolated.


Greg: in contrib\masmx86, different implementations of longest_match()
are selected on the fly. True, you cannot select those by yourself, but
an ASM implementation can be accompanied by a function that allows to
select the user's preference, then match_init() can take care of the
initialization. Otherwise, in the standard code base, match_init() is
just an empty stub.
