1) This is very interesting stuff.
2) But it really belongs on R-devel, not R-help. R-help is for helping
users with installing and using R, not debating its future or
discussing technical issues. Could I ask you to subscribe and then we
move the discussion there? (Don't worry, R-devel is not a very high
volume list.)

Same thing here.

I tried essentially the same stunt, but couldn't figure out how to get
the Windows console and graphics going, "Multiple Document Interface"
and all that. In particular, there's trouble with the gnuwin header
files versus the MS Platform SDK used in the sources. Does this mean
that you have a version running just like the "official" one? And
could it run under Win3 too?

I wouldn't be surprised, although Watcon does some register-passing
tricks, which one would think made it faster, (as well as incompatible
with other C compilers...!)

In the R-snapshot at CRAN (src/devel), I think. The very latest
versions are on Roberts computer...

Hmm. I don't know exactly what you mean here. I don't think that there
is a true writeup documenting any of this.

Definitely!
If yes, I can make it available.

How about the cross-compilers?

Agreed, but binaries (of R *and* all the packages) will in a
not-so-long perspective be needed for practical people.

Hmm. Does this line in src/regex/WHATSNEW ring a bell? (Not that I
know what I'm talking about, I just use grep...)
you have to build regex.h explicitly by "make h". The two known bugs

This sounds interesting. An alternative that I have been playing with
is to use Tcl/Tk, with a longer term perspective of developing R/Tk
language bindings like in STk (Scheme/Tk). This could have the benefit
of automatic (hah!) *Mac* portability.
Note, BTW, that some substantial changes have been made in the
nonreleased 0.62 version (see aforementioned snapshot) to the parser
and I/O parts, specifically to cater for windowing systems.
