I have been after a public domain C compiler for decades.
None of them reach C90 compliance. SubC comes the
closest but was written without full use of C90, which
makes it difficult to read. I'm after C90 written in C90.

A number of people have tried, but they always seem

preprocessor was done, but the attempt (by someone
else) to add C code generation was abandoned.

Also, my scope is limited - I am only after enough
functionality to get my 80386 OS (PDOS) compiled,
and I don't mind short=int=long = 32 bits, I don't
mind not having float. I don't use bitfields.

But I don't really know what I'm doing (I do know some
of the theory - but this is a particular design).

E.g. now that I have managed to get a variable passed to
a function, I now want the address of that variable passed
to the function - ie I want to do &x instead of x - and I am
not sure whether to create a new ADDRESS type, or
whether it is part of VARREF or what - in the original
(incomplete) concept. Or CC_EXPR_AMPERSAND.

I am happy to do the actual coding work - I'm just looking
for some nudges in the right direction if anyone can assist.

Thanks. Paul.

you mean there is no such a compiler? rise a fund for some to
write it and they will write it..and if few thousand of people
will give some money there it will be written

c compiler imo needes something like about form few months to about year
of coding of 1 person probably if he is somewhat experienced and healthy
so the cost i would probably estimate as prbably something like from 100k maybe 200k maybe 300 k dollars/euros depending on things
(raw cost imo could be more like 100-150k maybe but the risk/taxes etc
could increase it, on the other thing there are people probably able to do things cheap)
  (im not a merchant so i dont know but something as this estimation imo)
