R-alpha: Compiling R with Microsoft Visual C++

[Rob Creecy]

I tried compiling R-0.50-a4 with Microsoft Visual C++ 5.0  on Windows NT
4.2
and have some problems.
I am doing this with the hope of being able to contribute to further
development of R
for Windows.

I followed the instructions in the R/src/windows directory, copying the
resulting files to my PC.
Most source files that are not  Windows dependent compile fine, others
such as
wincons.c, plotmath.c do not. I have noticed some missing header files:
<env.h>                not in my compiler distribution
<dl.h>                   is this HP specific? presumably not needed
shellapi.h

I am also not sure if all the needed symbols  and compiler options are
being
properly defined at compile time.
If a working makefile could be made available it might give me some
clues
about how to proceed.

Any suggestions?
