[R] problem with Rcmd check

[Prof Brian Ripley]

Thanks to some debugging by Duncan Murdoch, it looks like this is a Perl
problem on Win98/ME at least.  As far as I can tell Perl's system command
calls command.com on that system, and at times that gets caught out by
line lengths and redirections.

So please let me know which version of Windows you have.

It's pretty unpredictable, and this did work on my Win98 mini-notebook
with a very small example (ash) but the undoc check failed there.
I was able to get it all to work by changing shell using COMSPEC, but
I cannot distribute the shell I did use.  Anyone know of a reliable
shell foo.exe for Win98 that uses `foo.exe /c commands...' ?  Otherwise
I can write a wrapper for sh.  Actually, I might be able to avoid the
shell here by using a list argument for system....

You might begin to see why Guido and I changed to NT about 2 years' ago.
