Subject pure C90 environment

For decades I have been working on creating a
public domain operating system called PDOS/386.
You can see the project here:

http://pdos.sourceforge.net/

About a week ago there was a major breakthrough -
the OS has become self-hosting, ie you can use
PDOS/386 to develop PDOS/386.

PDOS/386 supports both a 32-bit MSDOS-like API
as well as some of the Windows console mode API.

The C library (PDPCLIB) has no extensions,
meaning all applications need to be C90-compliant,
and my focus is on porting all C90 applications
to this new platform.

If an application wishes to use Posix open() it
is expected to provide its own mini-posix source
file called e.g. unixio.c, which makes open()
call fopen(). This was how GCC itself was ported,
to the pure C90 environments of both MVS and
PDOS/386.

I also ported micro-emacs, which necessarily
used the MSDOS API to provide functionality,
instead of being C90-compliant, but that is
the only exception so far. The alternative is
to make people use edlin, which I have C90
source for.

Anyway, I was wondering if any C fans had a
desire to see or use a C90 environment, with
a view to making it "clean". I don't yet have
a working "make", but I think "make" can have
a pure C90 target, that assumes all files are
out of date, since C90 doesn't provide a way
to get timestamps of files.

But everything is up for grabs in this new
environment. I am thinking that if I have pure
C90 code it can be run on MVS/380 and MVS 3.8J
too. I am a bit directionless at the moment,
and still trying to rationalize what I am
trying to achieve, other than I'm a big fan
of C90, the universal language for computers.

BFN. Paul.
