Problem with dir.create (R2.2.0 Windows XP 2002 SP 2)

No problem for me (Version 2.2.0  (2005-10-06 r35749), WinXPPro SP2):
setwd("q:/")
print(dir.create("q:/Andy/what/is/this", recursive=TRUE))
[1] TRUE
setwd("c:/")
print(dir.create("q:/Andy/what/is/that/thing", recursive=TRUE))
[1] TRUE

I've run into a problem with dir.create on R2.2.0 Windows XP 
2002 SP 2.

setwd("d:/")
print(dir.create("d:\\otis-sim\\rdata", recursive=T))
print(dir.create("d:\\otis-sim\\", recursive=T))

Both return false and fail to create the directories.

setwd("c:/")
print(dir.create("d:\\otis-sim\\rdata", recursive=T))

Returns true and succesfully creates the directories.

Why does this occur?

One comment is that Windows does not like trailing directory separators as 
in

print(dir.create("d:\\otis-sim\\", recursive=T))

and so this will give a warning as in
print(dir.create("d:\\otis-sim\\", recursive=T))
[1] FALSE
Warning message:
'd:\otis-sim\' already exists

Beyond that, the code is designed for Unix-like file systems and does not 
expect drives.

setwd("d:/")
print(dir.create("\\otis-sim\\foo", recursive=T))

seems to work reliably.  The issue seems to depend on what the current 
directory on the drive is (if a drive is specified), and I've made an 
adjustment for 2.2.1 to workaround that.

No problem for me (Version 2.2.0  (2005-10-06 r35749), WinXPPro SP2):

setwd("q:/")
print(dir.create("q:/Andy/what/is/this", recursive=TRUE))
[1] TRUE
setwd("c:/")
print(dir.create("q:/Andy/what/is/that/thing", recursive=TRUE))
[1] TRUE
