Ok. I am here.

(a) The gnuwin header miss some definition used by R. I hand copied
them (they are long but not too much) from the header of
a old Borland compiler (16 bit; so I also crossed my finger).
I do not know if hand copy is correct but I mean "a copy made
by my finger not using the cut and paste". Since now
the header are freely available but non redistribuible I
suppose that this is legal.
(b) So I have a version of R that "works".
"works": - I could run all the demos but the dynload one (I didn't
- I played with it for an hour preparing the
slides for my lesson of this afternoon (poisson regression
- I make use of the functions in the eda library (dynloaded).
and I tried some silly homemade dll.
(c) Running as the "official" one? No. The basic problem are
with the R sources that load data/library...
The system.win file, the one that I used from R-0.61.1, has
a not working "library" (also but perhaps I make some mistake a
For example to run the demos I used a silly ad hoc data function

Hence this part must be fixed. This is why, yesterday, I asked
for documentation of what must go in src/library/base/system.
Perhaps, it was an inappropriate request since I can
look to the unix one. But, you know. After, some hours
I had the system running but I could not do "data(iris)"
and with "no iris data there is no statistics".
(d) About Win30. I don't know.

I just compare the time of
for (i in 1:1000) a<-solve(matrix(rnorm(100),10,10))
matrix and the gnuwin32 version was 20% faster.
I suppose that this is not a fair test since
is biased towards the comparison of the fortran code (and I used g77).

If you want, I can make the patch available in a couple of days.
I just want to recompile from the scratch so that you have not
to bother about the fact that I have forgotten a file o something
like this. But I have now time today and tomorrow (teaching,

I suppose that if you have gcc running somewhere and configured
to support win32 as target you can cross-compile.
But, I have not tried.

Ok. But with a stable distribution.

Thanks. So regex.h must be built. The line before the one
that you quoted say that regex.h is generated by mkh.
What kind of monster mkh is?
