Hello,

I think there is a problem in recent devel builds of R on Windows with
various devices from the grDevices package.
For example:

> capabilities()
    jpeg      png     tiff    tcltk      X11     aqua http/ftp  sockets
    TRUE     TRUE     TRUE     TRUE    FALSE    FALSE     TRUE     TRUE
  libxml     fifo   cledit    iconv      NLS  profmem    cairo
    TRUE    FALSE     TRUE     TRUE     TRUE     TRUE    FALSE
> jpeg()
Error in jpeg() : unable to start jpeg() device
In addition: Warning messages:
1: In jpeg() : Unable to load Rbitmap.dll
2: In jpeg() : opening device failed

In the GUI version, a dialog appears saying:
Unable to load
'C:\PROGRA~1\R\R-213~1.0DE\library\grDevices\libs\Rbitmap.dll'

It seems that there should be an architecture folder (i386 or x64) after
"libs", because that is where the dll is located.

Same thing happens with png(), tiff(), etc.
