What matters is whether you have something to say about
programming in C or about the C language.  Your compiler
isn't written in C so anything you have to say about the
compiler itself isn't relevant here, whether or not it
should be taken seriously.

In talking about how the compiler behaves, you don't say
anything that pertains to the C language.  I don't think
this notion is very hard to understand.  Talking about the
environment in which the compiler is built, even though it
might be interesting in other contexts, still has nothing
to do with the C language.

No one knows but you, and it's not even clear if you know.
Ironically, if you were to go through and make up a list of
differences between what your compiler accepts and what the
C standard requires, and present that list here, that WOULD
be topical, especially if there were reasons related to how
easy or hard some aspects of C are to compile.  For reasons
beyond understanding you leave out exactly the pieces of
information that would make it relevant in comp.lang.c.  I'm
at a loss to understand why you do that.

An informal definition is a lot better than no description
at all, and at least is something about the C language.
So figure out what the discrepancies are (and only you can
do that), and tell us about it.  That's why we're here!

There's nothing wrong with feeling pride in having written
a fast program (in a non-C language), but it's not a subject
of interest in this newsgroup.

What would be relevant and possibly interesting is to say
what C language constructs you think should be considered
or left out.  Not what constructs IN OTHER LANGUAGES you
think are nice but what additions or changes to C you think
could add value.  Explain what, and leave it at that;  let
other people form their own opinions about how valuable
each change might be.
