[Rd] Rcmd check fails on Windows Samba network path in R 2.9.1

[Kevin R. Coombes]

Hi,

The problem almost certainly has something to do with Samba.  We also 
have a NetApp file system, and copying the package source to that drive 
and running Rcmd check from Windows works just fine.

When running the commands from an interactive R session, file_test 
returns TRUE and file.access to test write permission indicates a 
failure, even though that information is incorrect.Here is a session 
transcript:

-----------------------------------------
 > getwd()
[1] "n:/krc/Umpire/R-Package"
 > lib <- "Umpire.Rcheck"
 > file_test("-d", lib)
[1] TRUE
 > file.access(lib, 2)
Umpire.Rcheck
           -1
 > dir.create(paste(lib, "testdir", sep='/'))
 > dir(lib)
[1] "00check.log"   "00install.out" "testdir"     
 > sessionInfo()
R version 2.9.1 (2009-06-26)

Again, this all worked (and still works) correctly in 2.8.1.
